Reverse-ldd

The 'ldd' command allows you to find the libs used by a particular program.
This is the reverse.

This tool allows you to right click on a lib (.so) file (in /lib, /usr/lib, /usr/local/lib, etc).
You can then find out which applications or programs are using the chosen lib file.

Lib files are things like /usr/lib/libpango.so.1.0 and so on....

This tool will (after a short wait) present you with a list of the apps which depend on your chosen lib, in your default text editor.

It requires tclsh (the tcl/tk shell) and of course therefore tcl/tk itself.
But don't worry, this is included in many Puppies by default.

And even if not, I have packaged "jimsh" in the pet file, which is a tiny tcl interpreter (61kb).

Warning!! This will replace "tclsh" with a link to jimtcl in /usr/bin!!
Backup /usr/bin/tclsh first (if you have it), before you install this!

NOTES:

You can type 'reverse-ldd /path/to/lib' in the terminal to run it that way...

This was built on puppy 4 (for Puplite) and regarding some threads around elsewhere, I'd thought I better share

Quite handy!
Thank you.

Thanks. Sounds just like what I have wanted.

Another (simple) way is to just create an LDD list, and then search it for a particular lib.

USAGE: dll-finder [app-dir]
note: edit "ED" to preferred editor
