How to run Shell script as a source

CA1490051 — Fri, 28 Sep 2007 07:48:37 GMT

Hi all,

I want to run a shell script through another shell script but as a source.

Ex - Test1.sh
#!/usr/bin/sh
source Test2.sh

where my Test2.sh will be
#!/usr/bin/sh
export HAI=hai

If give ./Test1.sh

I says
Source not found .

can any one please suggest a solution for this

thanks in advance
Vikram

Hi Vikram:

Sourcing (reading) is done thusly:

#!/usr/bin/sh
. ./Test2.sh

That is, you specify a dot, a whitespace (space, tab) and the name of the file that you want to source (read).

See my other example in your first post using a Perl script, too.

Regards!

Shalom,

Assuming the code is compatible.

. ./scriptname

dot space ./scriptname

If you are in the same directory

... and one very important aspect of a sourced script is that it must not do an exit or a return because the sourced file is part of the foreground process. If you exit the sourced file, you exit the process.

And as fas as I know you don't have to write #!/usr/bin/sh in your sourced script...

but it doesn't hurt and will change the output of file(1) from "ascii text" to "commands text".

"source file" is the C-shell syntax.
". file" is the Bourne[-like]-shell syntax.

/usr/bin/sh is a Bourne[-like] shell.

Hi (again):

> Steven: "source file" is the C-shell syntax.

It is also a built-in in the Bash shell ('bash'). There, either the dot syntax or the 'source' builtin can be used to import variables into the current environment.

More precisely, it IS the Posix shell.
(The Bourne shell are not the droids you seek. You should only mention ksh and Posix shell. ;-)
