linux - Adding an || regex to a bash ``ed one-liner in a perl script -

i trying add || regex bash ``ed one-liner in perl script, if makes sense.

my $result = `df -h | grep -ve '^filesystem|tmpfs|cdrom|none'  | awk '{ print \$1 "\t" \$5 " used."}'`;   # .private maybe same /dev/sdb1 i'm trying remove  # trying add || (m/\.private/) above  print  "$result"; 

so removing lines output start filesystem, tmpfs, cdrom or none, @ present, , "or lines containing .private" one-liner, if possible...

i have below also, want reproduce results above code...

my @result2 =shell::df ("-h");  shift @result2;   # rid of "filesystem..." for( @result2 ){ next if ((/^tmpfs|tmpfs|cdrom|none/) || (m/\.private/)); @words2 = split('\s+', $_); print $words2[0], "\t", $words2[4], " used\.\n"; } 

you need add \.private part current regexp:

grep -ve '^filesystem|tmpfs|cdrom|none|\.private' 

on side note, pattern ^filesystem|tmpfs|cdrom|none might not want, filesystem matched @ beginning of line, other parts matched if appear anywhere in input. match them @ beginning, change to:

'^filesystem|^tmpfs|^cdrom|^none'
