Subject: all softlinks to a given file
Do you know an easy (fast) way to find all the softlinks to a given
file, using Fedora?
Example: in case of "S1 -> F, ...., SN -> F" the task is to find
S1, ..., SN given file F.
Any idea is appreciated,
----------------------------
Tough question... since links are one way... Here are some thoughts. Assuming that you're only looking at one filesystem, try to look at the inode numbers. Here is the initial directory listing:
% ls -li
3815190 -rw-r--r-- 1 jminer iis 0 Sep 28 16:21 F
3815193 lrwxrwxrwx 1 jminer iis 1 Sep 28 16:22 S1 -> F
3815215 lrwxrwxrwx 1 jminer iis 11 Sep 28 16:23 S2 -> ../jminer/F
The first number is the inode, and the file and each link has a distinct inode number. Modify the args to `ls` and you can derefernce the symbolic link:
% ls -Lli
3815190 -rw-r--r-- 1 jminer iis 0 Sep 28 16:21 F
3815190 -rw-r--r-- 1 jminer iis 0 Sep 28 16:21 S1
3815190 -rw-r--r-- 1 jminer iis 0 Sep 28 16:21 S2
So you would have to traverse your filesystem looking for links (S#) that derefernce to the same inode as the known file (F). You can do this with `find`
% find . -type l -exec ls -Lli {} \; | awk '$1 == 3815190 {print $0}'
3815190 -rw-r--r-- 1 jminer iis 0 Sep 28 16:21 ./S1
3815190 -rw-r--r-- 1 jminer iis 0 Sep 28 16:21 ./S2
