With an alias for "cd" as "pushd"...
-------------------------------
#!/bin/sh
alias cd=pushd
(cd test; ls) | while read file
do
echo -- $file --
done
-------------------------------
$ ./changedir
-- /tmp/test /tmp --
-- 1 --
Not exactly the same, but close... Probably better not to have your "cd"
grouped with the "ls" anyway. Still, can't reproduce your output...
...
PREVIOUS=$(pwd)
cd test
for i in $(ls -1); do
echo "-- $i --"
done
cd "$PREVIOUS"
...
Or you could use pushd/popd (but they're bashism's, as is "read"
apparently...).
