Bash script to change parent shell directory [duplicate]
You can technically source your script to run it in your parent shell instead of spawning a subshell to run it. This way whatever changes you make to your current shell (including changing directories) persist.
source /path/to/my/script/scriptor
. /path/to/my/script/scriptBut sourcing has its own dangers, use carefully.
(Peripherally related: how to use scripts to change directories)
Child processes (including shells) cannot change current directory of parent process. Typical solution is using eval in the parent shell. In shell script echo commands you want to run by parent shell:
echo "cd $filepath"In parent shell, you can kick the shell script with eval:
eval `sh foo.sh`Note that all standard output will be executed as shell commands. Messages should output to standard error:
echo "Some messages" >&2command ... >&2
