Hi I am getting an syntax error in expr i am trying to go thru each and every file under one directory and its subdirectory getting the no of lines in each file and keep on adding it, i need to know the total no of lines of code done i tried running expr command outside its working fine......any idea am i doing something wrong #! /bin/sh count=0 for values in `find .` do echo "$values" linect=`wc -l $values` echo " line no in $values is $linect" count=`expr $count + $linect` echo "total count $count" done

Hello, Assign count to avariable.. pass=count and then count=`expr $pass + $linect` I think it will work.. Thanks Swapan

I tried assinging count to pass but than also it gives syntax error for expr the expr works for simple addition z=`expr $x + $y works fine if x and y are defined any idea Mehul

Hi: Your problem probably is the fact that command: wc -l filename returns the number of lines and the filename. Either do this: cat filename|wc -l or wc -l filename|awk ' { print $1 }' Regards, Nails

If you're not limited to sh, Korn shell does arithmetic much better: #!/bin/ksh integer lines count=0 for file in $(find . -type f) do lines=$(wc -l $file | awk '{print $1}') (( count += lines )) print "$file: $lines lines. Running total: $count" done On my system (FreeBSD) I had to add the awk expression to wc -l in order to strip the filename that wc includes with the output.
