Usage

Overview

Options

-p, --preview

Display changes in a human reviewable format (the specifics of the format are likely to change in the future)

-F, --fixed-strings

Treat FIND and REPLACE_WITH args as literal strings

-n, --max-replacements=LIMIT [default: 0]

Limit the number of replacements that can occur per file. 0 indicates unlimited replacements

-f, --flags=FLAGS

Regex flags. May be combined (like `-f mc`).

c - case-sensitive

e - disable multi-line matching

i - case-insensitive

m - multi-line matching

s - make `.` match newlines

w - match full words only

-A, --across

Process each input as a whole rather than line by line. This allows patterns to match across line boundaries but uses more memory and prevents streaming

-h, --help

Print help (see a summary with '-h')

-V, --version

Print version

<FIND>

The regexp or string (if using `-F`) to search for

<REPLACE_WITH>

What to replace each match with. Unless in string mode, you may use captured values like $1, $2, etc

[FILES]

The path to file(s). This is optional - sd can also read from STDIN.

Note: sd modifies files in-place by default. See documentation for examples.

Exit status

0

Successful program execution.

1

Unsuccessful program execution.

101

The program panicked.

Examples

String-literal mode

$ echo 'lots((([]))) of special chars' | sd -F '((([])))' ''
lots of special chars

Regex use. Let's trim some trailing whitespace

$ echo 'lorem ipsum 23 ' | sd '\s+$' ''
lorem ipsum 23

Indexed capture groups

$ echo 'cargo +nightly watch' | sd '(\w+)\s+\+(\w+)\s+(\w+)' 'cmd: $1, channel: $2, subcmd: $3'
cmd: cargo, channel: nightly, subcmd: watch

Find & replace in file

$ sd 'window.fetch' 'fetch' http.js

Find & replace from STDIN an emit to STDOUT

$ sd 'window.fetch' 'fetch' < http.js
