Searching for lines ending with }
I'm trying to search for lines ending with "}" with the following command but am not getting any output.
Code:
grep '\}$'  myFile.txt

I actually want to negate this (i.e. lines not ending with "}"), but I guess that should be easier once I find the command that finds it?

this should do the work (put it inside a script) :

Code:
#!/bin/ksh

file=$1

typeset -i lineno=0

cat $file |
while read line
do
  lineno=lineno+1
  nline="${line%\}}"

  if [ "$nline" != "$line" ]
  then
    echo "$lineno ends in }"
  fi
done

Use the -v option of grep:

Code:
grep -v '}$' myFile.txt

Nope this does not give any output either. Smilie

Hi ,

Though Franklin's option works may be you can also try this

awk '{if($0~"}$"){print $0}}' <filename>

Hope this helps

Could it be that the lines do not end with exactly the '}' char? Try this:
Code:
$ grep -Ev '}\s*$' file

Thanks. That did the trick. But can't seem to figure out how to negate this now?

BTW still can't understand why grep doesn't match this? Smilie
