search contents of a file and use it to name the file
Hi All!

I have text files containing data as follows:

file1 file2 file3 file4

abc pqr def ghi
76 43 34 3
43 34 3 23
34 3 89 8

i would like to search the contents of all files for the unique string "def" and save the contents of the entire column in a new file called def.txt


Thanks,

Po

See if this works for you:
Code:
#!/usr/bin/ksh
mStr='def'
set -A mFld N/A $(sed -n "/${mStr}/p;q" input_file)
typeset -i mInd=1
while [[ ${mInd} -le ${#mFld[*]} ]]; do
  if [[ "${mFld[$mInd]}" = "${mStr}" ]]; then
    cut -d' ' -f${mInd} input_file > ${mStr}.txt
    break
  fi
  mInd=${mInd}+1
done

Since there are multiple input files, giving a single input file does not serve the purpose

what about simple grep command ?
Code:
grep -w "def" *.txt >> def.txt

use cut command or awk command to eliminate the filename (output of the grep command )
