It depends which shell, but one of these two usually works:

. var

or

source var

I'm not sure about ksh, but I'd imagine both would work.

Does a file named "var" exist in the current directory? – ams Jul 08 '13 at 15:26

. ./name_of_the_var_script

That’s dot + space + dot + slash + filename (because the “dot” utility needs an absolute or relative path to your var script).

You do need to specify the correct path ("$(dirname "$0")" as below usually works). – mirabilos Jul 08 '13 at 16:04

use the . (dot) command to source the file

. var_script

A note:

if the filename does not contain a slash then bash will attempt to find it in the $PATH.
if not found in the PATH, the current directory will be used (unless bash is in POSIX mode).

Ref [the . command][source] in the manual.

So, if you know where it is, use a relative/absolute path for it. [source]: https://www.gnu.org/software/bash/manual/bash.html#index-_002e

If that file is in the same directory as the "main" script, then `. "$(dirname "$0")"/fct_commun.sh` – glenn jackman Jul 08 '13 at 15:34
