Command line search and replace utility
npm install node-replace> Maintaned Fork from harthur/replace
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.
npm install node-replace -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
command. It's like grep, but with replace's syntax.`
search "setTimeout" . -r
Programmatic Usage
You can use replace from your JS program:javascript
var replace = require("node-replace");replace({
regex: "foo",
replacement: "bar",
paths: ['.'],
recursive: true,
silent: true,
});

By default, and search will exclude files (binaries, images, etc) that match patterns in the "defaultignore" located in this directory.$3
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`.
