Shell Programming and Scripting

Hi, I have a directory of files with filenames all in the format of xxx_yyy_zzz.pdf
Where xxx and yyy changes each filename but zzz stays the same. For example: File 1: Gold_Car_Vehicle.pdf; File n: Red_Truck_Vehicle.pdf.

I need to cycle through each file and output a Text File with 2 columns. The two columns are xxx and the complete name of the pdf.

So, in the case of the two Files above, my text file would read:

Code:

Column 1            Column 2
Gold            Gold_Car_Vehicle.pdf
Red             Red_Truck_Vehicle.pdf

So far I have the script:

Code:

#!/bin/sh

set -e
for f in *.pdf
do
  d=${f%_*.*}
  for drt in $(IFS=_;echo $d)
  do
    d=${f%_*.*}
    if [ ! -d "$drt" ]; then
      echo "$drt"
      echo "$f"
    fi
  done
done

What am I missing?

This should work:-

Code:

for file in *.pdf
do
        echo "${file%%_*} $file"
done

Thanks Yoda, that worked!
