List of file names

Shell Programming and Scripting
1

I have the following list of file names stored in $fnames, so that if I do

 
  foreach f ($fnames)
    echo "$f"
  end

I will get

n02-z30-sr65-rgdt0p50-dc0p002-16x12drw-run1
n02-z30-sr65-rgdt0p50-dc0p002-16x12drw-run2

n02-z30-sr65-rgdt0p50-dc0p01-16x12drw-run6

I want to create a list of the various filenames without the -run tag.

In other words, I want to have the list

n02-z30-sr65-rgdt0p50-dc0p002-16x12drw
n02-z30-sr65-rgdt0p50-dc0p004-16x12drw
n02-z30-sr65-rgdt0p50-dc0p006-16x12drw
n02-z30-sr65-rgdt0p50-dc0p008-16x12drw
n02-z30-sr65-rgdt0p50-dc0p01-16x12drw

foreach f ($fnames)
    echo "${f%-*}"
  end

I'm using csh and didn't seem to work

Try...

foreach f ($fnames)
    echo "$f" | sed 's/\(.*\)-.*$/\1/'
  end
