Just annotations of little "how to's", so I know I can find how to do something I've already done when I need to do it again, in case I don't remember anymore, which is not unlikely. Hopefully they can be useful to others, but I can't guarantee that it will work, or that it won't even make things worse.

Not even linux can create symlinks on FAT32

Posted 11-05-2014 at 02:04 AM by the dsc (linux-related notes)

If you've only briefly dealt with NTFS on linux, you might have noticed that it's possible to create symlinks there, not like the fake "shortcuts", but actual symlinks, that linux read as such.

That may lead the naive mind to think that symlinks are a linux/OS-side feature, and that therefore linux could create symlinks on FAT32. But that's going to be proven wrong on the first attempt.

You can, however, have symlinks on non-FAT partitions pointing to a FAT...

Tip: creating symlinks to another folder

Posted 09-01-2013 at 08:46 PM by the dsc (linux-related notes)

The syntax of "ln" requires full path information of the "source" file. Therefore, if you issue something like "for file in *.foo ; do ln -s ./$file /other-folder/somewhere/$(echo $file | sed s/foo/bar/) ; done", the produced symlinks will be empty.

To avoid that, the command must be:

for file in *.foo ; do ln -s $PWD/$file /other-folder/somewhere/$(echo $file | sed 's/foo/bar/') ; done

$PWD, the environment variable of the...

Batch-fixing symlink targets

Posted 08-28-2010 at 07:08 PM by the dsc (linux-related notes)
Tags batch, symlink

Sometimes you move the folder to which lots of symlinks were pointing, or something to that effect, and you want to simply "edit" these symlinks rather than recreating them pointing the correct new location. That's how it can be done with one line:

Code:
find /place-where-the-null-symlinks are/ -type l | while read nullsymlink ; 
do wrongpath=$(readlink "$nullsymlink") ; 
right=$(echo "$wrongpath" | sed s'|/whatever/is/the/old-wrong/path|/correct-new/path|')
