This might work on some systems using some shells, but there are a few problems:If the intent is to move into the directory containing a file named example.txt and do something in that directory for each directory that contains a file by that name, something more like:

Code:

#!/bin/ksh
spot=$PWD
find . -name 'example.txt' | while read -r path
do	file=${path##*/}
	dir=${path%/*}
	if ! cd "$dir"
	then	continue
	fi
	printf 'Process file "%s" in directory "%s"\n' "$file" "$dir"
	# do whatever you want to do in this directory...
	cd "$spot"	# return to the directory in which we started
done

This was written and tested using a Korn shell, but this should work with any shell that performs the basic parameter expansions specified in the POSIX standards.
