Git Pull from Shell script

Question

I'm trying to update a git repo from a bash script and I've run into some trouble. I can run git pull and have it work if there is no other lines or characters after the git pull but if I say have

#!/bin/bash
git pull
echo "test"

then I get

' is not a git command. See 'git --help'.

Did you mean this?
        pull

in the terminal instead of it actually doing the git pull.

Does that file have DOS newlines? Does running dos2unix on that script help? — Etan Reisner

use apt-get install git if you have UNIX based system, install git manually if you have window based system. — Ioan

As @EtanReisner suggested, you make actually be running git pull\r. — konsolebox

@Ioan They clearly have git installed as they are getting an error message from git. — Etan Reisner

You have to do dos2unix first like Etan mentioned. I can regenerate the same error if I do the reverse (i.e. unix2dos)

$ cat 1.sh

#!/bin/bash

git pull
echo ----

$ ./1.sh

fatal: Not a git repository (or any parent up to mount parent /cygdrive)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
----

See above, git pull command worked but with a valid error message that no repo mentioned after pull as im doing first time. That means git exists (if you do which git you'll see valid git executable location).

$ unix2dos.exe ./1.sh

unix2dos: converting file ./1.sh to DOS format ...

Now, my file is in DOS format (and Im running the script in Linux machine). Are you using Cygwin?

$ ./1.sh

./1.sh: line 2: $'\r': command not found
' is not a git command. See 'git --help'.

Did you mean this?
        pull
----

OK, convert it back to Unix line ending chars using dos2unix

$ dos2unix.exe ./1.sh

dos2unix: converting file ./1.sh to Unix format ...

$ ./1.sh

fatal: Not a git repository (or any parent up to mount parent /cygdrive)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
----

It works as expected.

OR try running with bash -x
