Bash script not found although it is in the $PATH

Question

On LMDE-based laptop I have a script upgrade.sh which only runs the following commands:

#!/bin/sh

apt-get upgrade
apt-get dist-upgrade

The script is in the /home/francois/scripts directory. I can easily run it from within this directory. It just works. Now I run the following commands:

$ sudo ln -s /home/francois/scripts /opt/scripts
$ sudo ln -s /opt/scripts /usr/local/bin/scripts

and create file /etc/profile.d/myscripts.sh

with just one line:

export PATH=$PATH:/usr/local/bin/scripts

I type

$ echo $PATH

and see that it contains /usr/local/bin/scripts

But when I run

$ sudo upgrade.sh

from any directory the system says that the command not found

ls -l shows -rwxr-xr-x 1 francois francois ...

Is your script actually marked executable? And you need a shebang for it to be executed by anything other than a shell. [Edit] the question to show file permissions (ie. output of `ls -l upgrade.sh`). — Charles Duffy, May 03 '17 at 14:38
...which is to say, this is fairly likely to be a duplicate of [How do I run a shell script without using `sh` or `bash` commands?](http://stackoverflow.com/questions/8779951/how-do-i-run-a-shell-script-without-using-sh-or-bash-commands), if it isn't duplicative of a `sudo`-specific question. — Charles Duffy, May 03 '17 at 14:38

...note that a *shell* will let you get away without a shebang line (`#!/bin/bash` or similar), but when launching software from any non-shell program (and `sudo` is not a shell!), it's strictly required. — Charles Duffy, May 03 '17 at 14:40
@CharlesDuffy You can definitely run a script that doesn't have a shebang with sudo. — 123, May 03 '17 at 14:51

Sudo doesn't inherit the caller's environment variables. $PATH is one of those variables.

To make it inherit the environment variables of the shell it's invoked from, run it as sudo -E [cmd]

Thank you. But I just tried it and still get: `sudo: upgrade.sh: command not found` – Francois Letelier May 03 '17 at 14:37
are you sure of this? the response provided looks to be OK since this is the way envs are passed on sudo commands. – Maurizio Benedetti May 03 '17 at 14:59
@MaurizioBenedetti Doesn't work for me, `sudo env PATH="$PATH" COMMAND` does though. – 123 May 03 '17 at 15:01

Yes, I'm baffled myself. I go to `/home/francois/scripts` and run script from there and it works. But after going to `'..'` it is not found! – Francois Letelier May 03 '17 at 15:03
