NAME

update - Greple module to update files

SYNOPSIS

greple -Mupdate

Options:

--update
--with-backup

--diff
--diffcmd command

VERSION

Version 0.02

DESCRIPTION

This greple module substitute the target file contents by command output. For example, next command replace all words in the file to uppercase.

greple -Mupdate '\w+' --cm 'sub{uc}' --update file

Above is a very simple example but you can implement arbitrarily complex function in conjunction with other various greple options.

You can check how the file will be edited by --diff option.

greple -Mupdate '\w+' --cm 'sub{uc}' --diff file

Command sdif or cdif is would be useful to see the difference visually.

greple -Mupdate '\w+' --cm 'sub{uc}' --diff file | cdif

This module has spun off from App::Greple::subst module. Consult it for more practical use case.

OPTIONS

• --update

• --update::update

  File is not touched as far as its content does not change.

• --with-backup[=suffix]

  Backup original file with ".bak" suffix. If optional parameter is given, it is used as a suffix string.

• --diff

• --update::diff

  Option -diff produce diff output of original and converted text.
