perl -pi -e "s/you/me/g" file
-e parameter allows Perl code execute
each line of text -p parameter to ensure that the processing and the processed results printed
-i parameter to modify the application of the results to a file (so not see the contents of the print -p)
-n represents over lines (similar to -p, but not responsible for printing results)
p4 revert
|
|
Revert only those files that haven't changed (in terms of content or filetype) since they were opened. |
|
|
Keep workspace files; the file(s) are removed from any changelists and Perforce records that the files as being no longer open, but the file(s) are unchanged in the client workspace. |
