in reply to Read .txt file -> append extension -> find on disc -> delete
Hi forro and welcome to the Monastery.
Here are some hints to get you going:
First correct the errors use strict; is giving you. Hint: my.
Do not forget to chomp( @text ); otherwise you could end up searching for somefileame\n.png which most likely does not exist.
Put the filenames from @text into a hash %files_to_find for easy lookup by using a for-loop or map. Decide if you want to create hash-entries for the filename only or for the two variations (filename.txt, filename.png). Creating hash-entries for both names (as keys) makes the wanted()-sub less complex but uses more memory. However, memory-consumption is most likely not an issue here unless you have several hundreds of million files in your remove.txt.
In the wanted()-sub, check if $files_to_find{$filename} exists.
Whether $filename is $_ (the filename w/o directory) or $File::Find::name
depends on
the format of the entries in remove.txt - i.e. if the entries are basenames or also
include the full path. You should also check if the file in question is a regular
file (-f).
If a match has been found, put the abs. filename in a @remove_these_files list for review and
removal in a later step.
Remove files from @remove_these_files after the FF-search. Make a backup and just print out what would have been removed before fiddling around with unlink.
Minor nitpick: The open() doesn't look right. Try open( my $file, '<', "remove.txt") or ..... Then read from <$file>. What you do works, but you create a file-handle file that's visible throughout your program. Usually not a good idea, but IMO tolerable for a small script. It might just be a good idea to get into the 3-args-open-habit early.
