Hi there, Need help here. In Unix,is there a way to coutn the total number of lines for all the files in a given directory? I know there is a comand called" "wc" which can count WORD, LINE, but it only can count 1 file at a time, not all the files in a directory. PLEASE HELP!

There are a lot of ways to code this, but for starters, you should be able to get your answer with wc -l * | tail -1 I did wc -l on a directory and got zero which is good. I don't know if that will hold true for all directories.

Hi there, It doesn't seem to count the subdirectory. It only counts the current directory. { ~/CrashDump} 136% wc -l * | tail -1 wc: XXX: Is a directory wc: YYY: Is a directory 233297 total Exit 1

You can discard those error messages: wc -l * 2> /dev/null | tail -1 Or you can target only the regular files, ignoring directories, links, and all the other file types: # !/bin/ksh fcount=0 lcount=0 for fname in *   do   if [ -f $fname ] ; then      ((fcount=fcount+1))      k=$(wc -l < $fname)      ((lcount=lcount+k))   fi   done echo "files=$fcount  lines=$lcount" files=100  lines=79123

There's an another way: find . -type f -exec wc -l "{}" \; | awk ' { sum += $1 } END {print sum}' Luke Chi
