Perl user login for unix command

Question

Can someone please help me with what I'm doing wrong here, scratching my head a bit. I don't know much perl, just making a small change to the irssi script.

$selectedname = <STDIN>; $Nameslist = `grep -i -w '$selectedname'~/file`; 

It works correctly with the problem I am facing, it looks like the variable is not inserted correctly. For example, if I type the same command using a word test on the command line, I get 3 lines that appear. But if I use the same word with this script, it becomes empty.

I know that it works correctly, because I can do * as input, and it will show me the whole file. It just does not work with the entered lines.

Any help would be greatly appreciated, it really pounded me.

In fact, when you use <STDIN> , a new line character appears. therefore you need to remove the new character string. you can use chomp to remove a new line character

The code:

  $selectedname = <STDIN>; chomp($selectedname); $Nameslist = `grep -i -w '$selectedname'~/file`;
