As pludi said, makefiles are great for this kind of job.
What you have is: to to create something, this otherthing must be done before.
A common place on source compilation is:
I need to build the executable, but first I need to build each individual object. Than I link all objects to produce an executable.
The beauty on Makefiles is that it "knowns" your source file has changed and build only that single file you need.
You can now run:
if you update file2.c, make sees it's timestamp is newer than corresponding file2.o and recompiles it, then relinks it into your executable.
To cleanup all objects:
And so on...
Nice, uh?
PS: That makefile was not tested, probably have some problems.
Hi All,
I need a script to compile multiple *.pli source files.

Thanks!

git-unpack-objects
GIT-UNPACK-OBJECTS(1) Git Manual GIT-UNPACK-OBJECTS(1)NAME
git-unpack-objects - Unpack objects from a packed archive
SYNOPSIS
git unpack-objects [-n] [-q] [-r] [--strict] < <pack-file>
DESCRIPTION
Read a packed archive (.pack) from the standard input, expanding the objects contained within and writing them into the repository in
"loose" (one object per file) format.
Objects that already exist in the repository will not be unpacked from the pack-file. Therefore, nothing will be unpacked if you use this
command on a pack-file that exists within the target repository.
See git-repack(1) for options to generate new packs and replace existing ones.
OPTIONS -n
Dry run. Check the pack file without actually unpacking the objects.
-q
The command usually shows percentage progress. This flag suppresses it.
-r
When unpacking a corrupt packfile, the command dies at the first corruption. This flag tells it to keep going and make the best effort
to recover as many objects as possible.
--strict
Don't write objects with broken content or links.
