I have bash script and it requires bash.
Another person try to run it with
sh script_name.sh
And it fails because sh is symbolic link to dash in his distribution.
$ ls -la /bin/sh
lrwxrwxrwx 1 root root 4 Aug 25 16:06 /bin/sh -> dash
I have an idea to use wrapper script:
#!/bin/sh
bash script_name.sh
The goal is to run .sh script by sh with bash in system having symbolic link to dash.
Well, usually you use the shebang to tell the shell to use the correct interpreter:
#!/bin/bash
# your script here
You have to set the script to be executable:
chmod +x my_script.sh
And let the user start it with:
./my_script.sh
It seems simple than to use a wrapper script.
You can use jbr test to run your script with bash even if the user use sh/dash or any sh like interpreter:
#!/bin/bash
if [ -z "$BASH_VERSION" ]
then
exec bash "$0" "$@"
fi
# Your script here
This way it correctly works with either :
sh ./my_script.sh
# or
bash ./my_script.sh
# or
./my_script.sh
