source command not found in sh shell

In Bourne shell(sh), use the . command to source a file

. filename

In certain OS's/environments (Mac OS, Travis-CI, Ubuntu, at least) this must be:

. ./filename

(Credit to Adrien Joly's comment below)

$ls -l `which sh`
/bin/sh -> dash

$sudo dpkg-reconfigure dash #Select "no" when you're asked
[...]

$ls -l `which sh`
/bin/sh -> bash

Then it will be OK

The source builtin is a bashism. Write this simply as . instead.

e.g.

. $FILE

# OR you may need to use a relative path (such as in an `npm` script):

. ./$FILE

This problem happens because jenkins Execute Shell runs the script via its /bin/sh

Consequently, /bin/sh does not know "source"

You just need to add the below line at the top of your Execute Shell in jenkins

#!/bin/bash

I faced this error while i was trying to call source command from #Jenkins execute shell.

source profile.txt or source profile.properties

Replacement for source command is to use,

. ./profile.txt or . ./profile.properties

Note: There is a space between the two dots(.)

The source command is built into some shells. If you have a script, it should specify what shell to use on the first line, such as:

#!/bin/bash

In case you cannot change the script to use "." instead of "source", change the link of "sh" to point to "bash" instead of "dash":

# which sh
/usr/bin/sh

# which bash
/usr/bin/bash

# ls -la /usr/bin/sh
lrwxrwxrwx 1 root root 4 Oct  5 15:55 /usr/bin/sh -> dash

# ln -sf /usr/bin/bash /usr/bin/sh

# ls -la /usr/bin/sh
lrwxrwxrwx 1 root root 4 Feb  6 09:18 /usr/bin/sh -> bash

source is a bash built-in command so to execute source command, you can log in as root.

sudo -s
source ./filename.sh

You have 2 options, switch from pure shell to bash which enables the bash features including source. https://superuser.com/questions/1220159/bash-prompt-variables-not-working/1764353#1764353

Or use . instead of source with this form

. ~/.your_file_name

for example

. ~/.bashrc

please consider one space between dot and tilde. Tilde (~) refers to the home directory, if your file is located somewhere above the home, use an absolute address from /

On Ubuntu, instead of using sh scriptname.sh to run the file, I've used . scriptname.sh and it worked! The first line of my file contains: #!/bin/bash

use this command to run the script

.name_of_script.sh

I had this same issue recently and solved it by changing the shebang from #!/bin/bash to #!/usr/bin/env bash

I found in a gnu Makefile on Ubuntu, where /bin/sh -> bash.

I needed to use the . command, as well as specify the target script with a ./ prefix (see example below).

source did not work in this instance, not sure why since it should be calling /bin/bash.

My SHELL environment variable is also set to /bin/bash.

test:
    $(shell . ./my_script)
