COMMON ISSUE ON WINDOWS

There is a built-in replace command on windows, if you get an error like this

``shell
Invalid switch - -h
No files replaced
`

You are using the windows replace

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.

Install

With node.js and npm:

npm install replace -g

You can now use replace and search from the command line.




Examples

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
`

Replace using stdin:

`
echo "asd" | replace "asd" "dsa" -z
`

See all the options:

`
replace -h
`

Search


There's also a search 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("replace");

replace({
regex: "foo",
replacement: "bar",
paths: ['./Test/'],
recursive: false,
silent: false,
});
`

More Details

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`.
