Shell Programming and Scripting

for d in dir/* do; [ -d "$d" ] && egrep -v "^`basename $d`$" file.txt > /tmp/file.$$ && mv /tmp/file.$$ file.txt || exit 1; done

Code:

bash: syntax error near unexpected token `['

There's no point to cramming a script on to a single line; all it does is make it harder to read and debug.

Code:

for d in dir/*
do
 [ -d "$d" ] &&
   egrep -v "^`basename $d`$" file.txt > /tmp/file.$$ &&
     mv /tmp/file.$$ file.txt ||
       exit 1
done

And basename, an external command, is not necessary:

Code:

for d in dir/*/
do
  egrep -v "^${d##*/}$" file.txt > /tmp/file.$$ &&
    mv /tmp/file.$$

Even at the prompt, I usually type multi-line commands; they're easier to read.

The standard Unix shell can do it without an external command.
