replace
is a command line utility for performing search-and-replace on files. It's similar to sed but there are a few differences:
- Modifies files when matches are found
- Recursive search on directories with -r
- Uses JavaScript syntax for regular expressions and replacement strings.
- Fork of no longer maintained harthur/replace
npm install replace3 -g
You can now use replace
and search
from the command line.
Replace all occurrences of "foo" with "bar" in files in the current directory:
replace 'foo' 'bar' *
Replace in all files in a recursive search of the current directory:
replace 'foo' 'bar' . -r
Replace only in test/file1.js and test/file2.js:
replace 'foo' 'bar' test/file1.js test/file2.js
Replace all word pairs with "_" in middle with a "-":
replace '(\w+)_(\w+)' '$1-$2' *
Replace only in files with names matching *.js:
replace 'foo' 'bar' . -r --include="*.js"
Don't replace in files with names matching *.min.js and *.py:
replace 'foo' 'bar' . -r --exclude="*.min.js,*.py"
Preview the replacements without modifying any files:
replace 'foo' 'bar' . -r --preview
See all the options:
replace -h
There's also a search
command. It's like grep
, but with replace
's syntax.
search "setTimeout" . -r
You can use replace from your JS program:
var replace = require("replace");
replace({
regex: "foo",
replacement: "bar",
paths: ['.'],
recursive: true,
silent: true,
});
By default, replace
and search
will exclude files (binaries, images, etc) that match patterns in the "defaultignore"
located in this directory.
If replace
is taking too long on a large directory, try turning on the quiet flag with -q
, only including the necessary file types with --include
or limiting the lines shown in a preview with -n
.
