FileName with trailing Pipe

[LAdProg2005]

Hello all,

i am trying to read file that has pipe in the end of file name.

fileOne| -> it is a data file

./test fileOne| doesn't work as it doesn't read the |

I tried to escape it with backslash
./test fileOne\| but this doesn't work also

$opF = $ARGV[0];

      open FILE, "$opF" or die "$!";
      while(<FILE>)
      {
        $line = $_;
        print "$line\n";
      }

any help will be appreciated
thank you
lad

Two things:
1. First you will need to quote the file name so your shell knows that you are not trying to pipe test.pl's output:
./test.pl "fileOne|"

2. Second, you should use the 3 argument mode of open.

Something like:

open FILE, '<', $opF or die "$!";

1. First you will need to quote the file name so your shell knows that you are not trying to pipe test.pl's output:
./test.pl "fileOne|"

For this, it still says
Can't exec "fileOne": No such file or directory at ./test.pl line 8.

Thanks

Try single quotes. Some shells (bash for example) try to interpolate things still inside double quotes (for example any $ in double quotes bash mistakes for trying to insert a bash variable).

perl -e '$|=$i=1;print" oo\n<|>\n_|_";x:sleep$|;print"\b",$i++%2?"/":"_";goto x;'

Tried that as well. It still doesn't work

bengR's second suggestion seems to fix it for me. What OS and shell are you using?

$ cat test
#!/usr/bin/perl -w
use strict;
my $opF = $ARGV[0];

open FILE, '<', $opF or die "$!";
while(<FILE>)
{
        my $line = $_;
        print "$line";
}
$ cat fileOne\|
