Perl: suppress output of backtick when file not found

backticks, exitstatus, perl, regex

Solution

By running it like

$status = `ls -l error* 2> /dev/null`;

and suppressing the external command's output to standard error.

If you just need the file names (and not all the other info that `ls`'s `-l` switch gives you), this can be accomplished in pure Perl with a statement like

@files = glob("error*");
if (@files == 0) { 
    ... there were no files ...
} else { 
    ... do something with files ...
}

and if you do need all the other info you get from `ls -l ...`, applying the builtin `stat` function to each file name can give you the same information.

Problem

In my code : ``` $status = `ls -l error*`; ``` It shows output : `ls *error No such file or directory.` How can I suppress this message. I am interested in determining that the error files are generated or not. If yes, I need the list of files else ignore (without printing the message)
