`chop` removes the last character of each argument. `chomp` removes the last character(s) of each argument if they're equal to the value of `$/`. `chomp` is useful in combination with `<$fh>` because `<$fh>` reads until the value of `$/` or eof is found.	[reply] [d/l] [select]

chop is used to remove the last character,chomp function removes only line endings. chop removes the last character and returns the character chopped. Chomp removes any trailing string that corresponds to the current value of $/ and returns number of characters removed.	[reply]

chomp function removes only line endings Only for a very specific definition of line endings. That's misleading. It won't even remove a Windows line ending (CRLF) on a Windows machine by default. Nor would you want it to do so.	[reply]

I suggest you follow and read the links contained in this posting (by AM) - then and only then, feel free to ask further questions - if you have any. A user level that continues to overstate my experience :-))	[reply]

Zap yourself too for linking to a specific PerlMonks domain. Better: `[id://750717\|Zzzzzzzzzzzap!]` Also available: `[href://?node_id=750717\|Zzzzzzzzzzzap!]` `<a href="?node_id=750717">Zzzzzzzzzzzap!</a>`	[reply] [d/l] [select]

Chomp is generally recommended over chop because chop can have unexpected results. For example, suppose all but the last line of a file ends in a new line. chomp will leave the last line intact (since it only removes $/) but chop will remove the last letter of the last line since it blindly removes the last character, whatever it is - probably not what you want.
