Question

I need to process the shared library dependencies of a library from a bash script. The for command processes word-by-word:

for DEPENDENCY in `otool -L MyApplication | sed 1d`
do
    ...
done

What is the way to process the results line-by-line?

Answer 1

You should use the read command.

otool -L MyApplication | sed 1d | \
while read i
do
  echo "line: " $i
done

See bashref for a description of the read builtin, and its options. You can also have a look at the following tutorial for examples of using read in conjunction with for.
