Code:
#!/bin/bash

while read a b c
do
   [[ "$a $b" == "version =" ]] && (( c++ ))
   echo "$a $b $c"
done < infile

NAME
minccomplete - checks if a MINC file is complete SYNOPSIS
minccomplete [options] <file.mnc> minccomplete is designed as a QC tool that you can use to check if MINC or xfm files have been completely written. DESCRIPTION
minccomplete will check if a file exists and is completely written. The reasons for non-completion are varied but typically caused when a process writing a MINC or xfm file is interrupted. A zero will be returned if the file is complete and a -1 if it isn't. Examples: $ minccomplete in.mnc 0 $ minccomplete in.xfm 0 A MINC file is returned as complete if the image attribute image:complete is set. ie: mincinfo -attvalue image:complete infile.mnc A xfm file is deemed complete if xfm2param can parse the file. The associated exit codes will also be set as part of this so that minccomplete can be used in scripts. An entirely simplistic example: #! /bin/sh infile=$1 if [ `minccomplete ${infile}` ] then echo "Yes!" else echo "Nope, try again" fi Problems or comments should be sent to: a.janke@gmail.com OPTIONS
-v, --verbose Be noisy when doing things --version Print version number and exit -h, --help Dump some quick help output --man Dump a man page -e, --error_string Don't die on errors (eg: file not found) and print the supplied value instead SEE ALSO
