yes, I know :-(. I was once tricked by this, a link removed, but from the trash can it still pointed to the data :-)

Because you have full path names, you're gonna have trouble. Since you're on the same disk, you should use relative links

I did them with Dolphin. Given my data structure it's pretty hard to make them in cli :-(

You're going to have to remake all of your links in any case; the question is whether you change them once to point relatively or make them absolute links again to the new disk ... and perhaps repeat in a few years :-) You can of course do this on the new disk and leave your old safe as a backup.

in fact, Dolphin allows me to edit the target, but the result is unexpected, I need to experiment more thanks jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

'mc' permits creation of links, or editing them later. I see options to create relative or absolute symlinks, or hardlinks. The obvious snag is that is a "text" tool, so if they are photos you see their names, not the contents. Not instantly, that is. There are GUI tools similar to 'mc', but not that powerful. I just looked at "gnome-commander", it does not seem to do links. Same thing with "krusader" - but this one does generate a tiny preview of files if you ask. -- Cheers / Saludos, Carlos E. R.

I use it pretty often (in fact I need it on any server), but never used it to link. Will get a look

works well. Not to edit previous links, but much faster than cli to create new. accceptable. thanks jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

in fact mc is very clever. I *can* edit the link target, replacing the absolute link part by ../../

Exactly :-)

wonderfull :-)

thanks to make me discover this option in my for long beloved mc :-))

isn't a lovely tool? I know some one, a geek, scientific, engineer, clever friend that makes fun of me when he sees me using mc and invents all sort of crazy histories, like me using Norton Commander in the past and so wanting something familiar now. Gosh. There simply doesn't exist a GUI tool that does as much as 'mc' does. Not counting that you can add menu entries with some sort of script language it has. -- Cheers / Saludos, Carlos E. R.

Like mc, it takes a while to discover all its power. I've been using Havard's File Commander for 27 years or more, as it was migrated from its OS/2 origin into Linux.

yet not a gui like dolphin :-(

Precisely why it's great, designed for touch-typing keyboard users, yet works in GUI, as it did in OS/2 in 1992, where it was one of many morphed off of John Socha's Norton Commander, before the first PC GUIs came to market. https://en.wikipedia.org/wiki/Norton_Commander#Norton_Commander-inspired_sof... -- Evolution as taught in public schools, like religion, is based on faith, not on science.

That is like "Tap Dancing On Landmines", or "Playing Russian Roulette". Perhaps I'm just jaded, or perhaps it's from 20 years of Linux experience, but you always want to create a maintain your data layout from the command line. There is never any ambiguity whether absolute or relative links are used, etc.. What you need to do on the new disk is figure out where all the file live relative to your "links directory" and then simply replace all absolute links with relative ones. Use the -f option to overwrite the absolute link with relative ones. E.g. $ ln -sf ../relative/path/to/target linkname You can probably build the list of links with the 'find' command an a '-type d' to select the directories needed and a '-name glob' You probably want to cd /path/on/new/disk/photos Then create a list of the directories you need to link relative to that location (you can redirect the output from find to a 'newlinks' text file if you need to edit it before creating the links). Then just loop over the contents of the 'newlinks' file replacing the symlinks on the new disk: while read -r newlnk; do ln -sf "$newlink" ## name will default to last component of $newlink done < newlinks Or if you want to give each of the symlinks a custom name, edit the 'newlinks' file and add a second column with the custom link name and do: while read -r newlnk lnkname; do ln -sf "$newlink" "lnkname" done < newlinks You can skip the 'newlinks' file an simply replace them all based on the output of `find` if there are no changes or edits needed. You may also be able to use globing "*/*", etc.. instead of find. It just depends on what the layout is. -- David C.

$ ln -sf ../relative/path/to/target linkname

'mc' allows direct edit of the target of a symlink. If you get it wrong, it tells you instantly that it is wrong by displaying it in red and with a '!' in front instead of '~'. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)

Are you linking directories only are all files? If you give a 'tree' (just a representative directory/file example), I"m happy to help you write a short script to automate rebuilding your links (I do something similar with photos in Gallery2) How you feed your loop will depend on how deeply nested your file storage is. You "day long" computing can be reduced to just a few minutes by avoiding spawning additional subshells within the body of your loop. The command-substitution with sed will require 2 subshells per-iteration. That is where your time comes from. With bash, parameter expansions will avoid the additional subshells. You can also do it all within a single call to awk which would be orders of magnitude faster. -- David C.

You need to either escape the '/' not used as sed's s/// command-delimiters or use other delimiters. And of course you need to use a command-substitution just as you did for the j=.

The task is 3-fold:

1. find symlinks with non-relative targets. 'find' can do that with: find -type l -lname '/*' ...

I don't need this part, I know where they are :-) (but it don't hurt :-)

2. Determine the link target and change only those with an existing target (a link target can contain arbitrary information). The 'readlink' tool does that with the -e option.

I know them as well

3. Create the same symlink in place with a relative target. 'ln' has the '-r' (--relative) option, and -f to remove the existing link.

This boils down to e.g.:

find . -type l -lname '/*' \ -execdir \ sh -c 'rel=$( readlink -e "{}" ) && ln -sfrv "$rel" "{}" ' \ \;

find will pass the link names where "{}" is mentioned in the above. Instead of having the shell code as -execdir argument one could of course also put it into a separate script.

No warranty - if you want to use it, then please test in a separate directory hierarchy first whether the result is what you want/need.
