perl -pi -e
The -i option in Perl will edit the specified file "in place", so you don't have to mess with moving files around.
% echo "eat food" >> test.txt
% echo "eat more food" >> test2.txt
% perl -pi -e 's/food/pie/g' *
% cat test.txt
eat pie
% cat test2.txt
eat more pie
-i takes an optional argument. If specified, a backup will be saved with the argument as the file's extension.
% perl -pi'.bak' -e 's/pie/chicken/g' *
% ls
test.txt test.txt.bak test2.txt test2.txt.bak
% cat test.txt
eat chicken
% cat test.txt.bak
eat pie

build-lives-rfx-plugin(1) General Commands Manual build-lives-rfx-plugin(1)
NAME
build-lives-rfx-plugin - builds rendered effects for LiVES
SYNOPSIS
build-lives-rfx-plugin script_name [plugin_dir] -get section file
DESCRIPTION
This perl script is used by LiVES to compile an RFX (rendered effect) plugin for LiVES. It is generally called from build-lives-rfx-plugin-
multi for a script which has a language code representing LiVES-perl. The script_name must be the full (absolute) path to the plugin
script, and plugin_dir can be used to specify the output directory where the compiled plugin should be generated. If plugin_dir is not
defined then /tmp is assumed.
The second variant with -get is used to print out a script section from a plugin script to stdout. It is generally only used internally by
LiVES.
Return values The script returns the following values
0 - success 1 - the value of a trigger was greater than the number of parameters 2 - a value could not be read from the script file 3 - the
language code of the plugin script was not equivalent to LiVES-perl 4 - the API version level of the plugin script was invalid 5 - the
<define> section was missing from the plugin script
