When working on large projects, I often need to make the same change across hundreds of files. My workflow in Vim has evolved to handle this efficiently. I start by setting up the environment with :set hidden so I can switch between buffers without saving. Then I load all relevant files using :args **/*.py (adjust the pattern as needed).
For simple replacements, I use :argdo %s/pattern/replacement/g | w. The 'g' flag replaces all occurrences in each file, and 'w' saves immediately. When I need more control, I prefer :cdo after running :vimgrep /pattern/ **/*.py. This shows me all matches first, and then I can use :cfdo %s//replacement/g to replace them all at once.
For complex replacements involving capture groups or special characters, I create a test file first. I practice my substitution pattern there until it works perfectly. Only then do I apply it to all files with :argdo. I always keep a backup of the original files until I verify the changes. This method has saved me from many potential disasters when refactoring code across entire projects.

replacing text across multiple files is a common task for me. The quickest way I've found is using the :argdo command. First, open all the files you want to modify with :args *.txt (replace *.txt with your file pattern). Then run :argdo %s/oldtext/newtext/gc | update. The 'gc' flags ask for confirmation before each replacement, and 'update' saves the file only if changes were made. For a safer approach, I sometimes use :argdo %s/oldtext/newtext/ge | update, where 'e' suppresses error messages if the pattern isn't found.
Another method I use is with the :cdo command after creating a quickfix list through :vimgrep /oldtext/ *.txt. This lets me review all matches before replacement. I find these methods more efficient than manually editing each file, especially when dealing with dozens of configuration files.

I've developed a reliable Vim workflow for bulk text replacement. My favorite method combines the power of buffers and substitutions. I start by opening all target files with :e *.conf, then populate the buffer list with :bufdo. Before making any changes, I run :wall to save all open files as a backup.
The actual replacement happens in two stages. First, I test my pattern on a single file using :%s/old/new/g. Once confirmed, I apply it to all buffers with :bufdo %s/old/new/g | w. This approach gives me better control than argdo since I can visually verify the changes in each buffer before saving.
For more complex scenarios where files are in different directories, I use :find combined with backtick expansion like :args `find . -name '*.php'`. Then I can run my substitutions across this file list. I always make sure to check a few files manually afterward to catch any unexpected replacements.

One Wife, Multiple Weddings
On the day of my wedding with my girlfriend, I was unexpectedly informed by the hotel that our ceremony had to be postponed by a couple of hours.
With no time to notify relatives and friends of the change, I had to rush to the hotel entrance to intercept guests.
Upon arriving, I was stopped at the door by security, who told me that a wedding was currently taking place inside.
The host's voice could be heard as I saw my girlfriend, wearing a veil, smiling and extending her hand to a man who was half-kneeling.
In the audience, all the bride's relatives who were supposed to attend our wedding were seated, clapping and cheering.
The man on stage was her dream guy and also my current superior.
Seeing me causing a commotion, my girlfriend warned me, "I'm just helping out. Alex is your superior. I'm also doing this to help you. Don't cause any trouble."
Just helping out? I had booked the wedding venue, chosen the time, designed the wedding dress, and personally sent out the invitations.
How could a wedding be rearranged so suddenly?
I looked coldly at the ring box the man was holding.
"It seems my taste is quite similar to my yours. If that's the case, this diamond ring is yours, including the wife."
My girlfriend finally panicked.

How To Undo A Replace Operation In Vim?
3 คำตอบ2025-07-15 04:47:55
I've been using Vim for years, and one of the first things I learned was how to undo a replace operation. If you accidentally replace text using the ':s/old/new/g' command, you can undo it by pressing 'u' in normal mode. This reverts the last change you made. If you've made multiple changes after the replace, you might need to press 'u' several times. For more control, you can use ':undo' followed by a number to undo a specific number of changes. Another handy trick is to use ':earlier' and ':later' to move through your undo history. It's a lifesaver when working on large files.
How To Replace Text With Confirmation In Vim?
3 คำตอบ2025-07-15 07:52:17
I've been using Vim for years, and one of the handiest tricks I've picked up is how to replace text with confirmation. Here's how I do it: start by typing `:%s/old_text/new_text/gc`. The `%` means it searches the whole file, `s` stands for substitute, and `gc` at the end makes it ask for confirmation before each replacement. Vim will show you each occurrence and ask if you want to replace it. You can hit `y` for yes, `n` for no, `a` to replace all, or `q` to quit. This method is super precise and prevents accidental replacements, which is a lifesaver when editing config files or code.
I also like to use `:set hlsearch` before running the substitute command. It highlights all matches, so I can see where the changes will happen. After I'm done, `:nohlsearch` turns off the highlighting. This combo keeps my edits clean and error-free, especially in large files where I need to be careful about what gets replaced.
How To Replace Special Characters In Vim?
3 คำตอบ2025-07-15 12:37:21
I use Vim daily for coding, and replacing special characters is something I do often. The simplest way is to use the substitute command. For example, to replace all asterisks with underscores, I type :%s/\*/_/g. The key here is escaping the special character with a backslash. If I need to replace tabs, I use :%s/\t/,/g to turn them into commas. For newlines, it’s :%s/\n/ /g to replace them with spaces. I also love using visual mode to select specific lines before running the substitution. It’s precise and saves time when dealing with large files.
Can You Replace Multiple Lines Of Text In Vim?
3 คำตอบ2025-07-03 15:31:10
I use Vim daily for coding and editing, and one of the most powerful features is its ability to replace multiple lines of text efficiently. To do this, I typically use the substitute command with a range. For example, if I want to replace 'foo' with 'bar' from lines 5 to 10, I'd type ':5,10s/foo/bar/g'. The 'g' flag ensures all occurrences in each line are replaced. This method saves me tons of time compared to manual editing. Vim's regex support also allows for complex patterns, making it even more versatile. If I need to confirm each replacement, I add a 'c' flag like ':5,10s/foo/bar/gc'. This workflow is a game-changer for bulk edits.
What Is The Vim Command To Replace A Word Globally?
3 คำตอบ2025-07-15 18:43:00
I've been using Vim for years, and one of the most powerful commands I rely on is global replacement. To replace a word everywhere in your file, you use the command `:%s/oldword/newword/g`. The `%` means the entire file, `s` stands for substitute, and `g` replaces all instances in each line, not just the first one. If you want to confirm each replacement, add a `c` at the end like `:%s/oldword/newword/gc`. This makes Vim ask for confirmation before changing each occurrence. It's a lifesaver when refactoring code or fixing typos across large documents.
How To Replace Text In Visual Mode In Vim?
3 คำตอบ2025-07-15 18:13:53
I've been using Vim for years, and visual mode text replacement is one of those tricks that feels like magic once you get the hang of it. When I need to replace text, I first highlight the area in visual mode by pressing 'v' for character-wise or 'V' for line-wise selection. Then, I hit ':' to bring up the command line, which automatically inserts "'<,'>" to indicate the visual range. From there, I type 's/old_text/new_text/' and press enter. The change applies only to the selected area, which is super precise. I love how this keeps my edits contained without affecting other parts of the file. For multiline replacements, I sometimes use visual block mode (Ctrl+v) to select a column of text—super handy for repetitive edits in code or config files.
What Are The Best Vim Commands To Find And Replace?
3 คำตอบ2025-07-26 15:15:15
I've been using Vim for years, and mastering find-and-replace commands has been a game-changer for my workflow. The basic command :%s/old/new/g replaces all instances of 'old' with 'new' globally in the file. To confirm each replacement, I use :%s/old/new/gc, which adds an interactive prompt. For case-insensitive searches, adding \c like :%s/old\c/new/g is super handy. I also love using visual mode to replace only within a selection—just highlight text, then type :s/old/new/g. For more complex patterns, regex with capture groups like :%s/\(pattern\)/\1_replaced/g saves time. Don’t forget :%s/old/new/gI to ignore case entirely!
What Are The Flags For Replace Text In Vim Command?
3 คำตอบ2025-07-03 05:57:38
I've been using Vim for years, and the flags in substitution commands are super handy once you get the hang of them. The basic syntax is :s/pattern/replacement/flags. The 'g' flag replaces all occurrences in the line, not just the first one. The 'c' flag makes Vim ask for confirmation before each replacement, which is great when you want to be careful. The 'i' flag makes the search case insensitive, while 'I' makes it case sensitive. There's also 'e' to suppress errors when the pattern isn't found. My favorite is 'n', which just counts the matches without actually replacing anything. These flags can be combined too, like 'gc' for global replacement with confirmation.
