I have PHP scripts that have code that I want to change from:


And I want the file to be changed to this:


I don't use regex very often so I am not sure how to key on the "_show();" on the end of each function. SED seems like the best function for this but any help is appreciated.

  • What are the rules for the names Function1, Function2? are they always composed of alphanumeric characters only? Aug 11, 2019 at 12:47
  • What are the names of those functions, do they always start with "Function_"? Is there always an underscore? Do they all end in "_show()"?

sed -i 's/\([A-Za-z0-9_]*\)_show();/call_my_func("\1");/g' *.php

The -i option sell sed to update the *.php files in-place.

This searches for alphanumeric text (including underscores) followed by _show(); and captures that text.

This whole string gets replaced by call_my_func(", the captured text, and ");.

This gets repeated if the match text occurs more than once because of the modifier g.

It would have been possible to use [a-z0-9_] without A-Z by using the i modifier, but then it would also match Function_SHOW(); which is probably not what is desired.

  • That is perfect. Thanks for the help!
