source command not found in sh shell

/bin/sh is usually some other shell trying to mimic The Shell. Many distributions use /bin/bash for sh, it supports source. On Ubuntu, though, /bin/dash is used which does not support source. Most shells use . instead of source. If you cannot edit the script, try to change the shell which runs it.


$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

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
