- Run a Perl script in debug mode, using `perldebug`:
|
||||
|
||||
`perl -d {{script.pl}}`
|
||||
|
||||
- Replace all occurrences of a string in a file with another string, overwriting the file in-place:
|
||||
|
||||
`perl -p -i -e 's/{{find}}/{{replace}}/g' {{filename}}`
|
||||
|
||||
- Same, saving an unmodified copy of the original file with a different extension:
|
||||
|
||||
`perl -p -i'.old' -e 's/{{find}}/{{replace}}/g' {{filename}}`
