You'd think there was something already built :D Here's one (messy) way
of doing it:
#!/bin/sh
FINDME=`ls -i $1|awk '{print $1}'`
find / -inum $FINDME 2>/dev/null
The problem, of course, is that you're doing a find for each run.
I was working on a way to use a combination of pwd and the passed name to
get an actual path. It would do this:
CURDIR='pwd'
RAWNAME=$CURDIR/$1
I would then look for any "../" in RAWNAME and remove the same number of
leading directories as occurrences of "../". E.g.
/home/kwan/rpm/RPM/../SPECS/../../../../bin/ls
would first reduce to:
/home/kwan/rpm/SPECS/../../../../bin/ls
Then to:
/bin/ls
You could probably do this with a regex by searching for the first
occurrecnce of "../" then removing the directory immediately preceding.
Loop through the RAWNAME until no more "../" exist. At this point you'd
have the fullname.
