Sorry Something cropped up and I did not check my emails.

are you saying your current link is already pointing to the latest version?

if so you can try this:
Code:
ls | grep -v Current | sort | sed '$d' | xargs rm -rf

If not, you can try this:

Code:
ls | grep -v Current | grep -v `ls -l Current | awk '{print $NF}'` | sort | sed '$d' | xargs rm -rf

Sorry for the double grep -v. Maybe someone can help to combine them..

Note that this will not work with names that contain spaces..

@Leion, dr.house I think xargs got mixed up with find syntax a bit there, no?

For directory names with spaces one could use this:
Code:
ls -d 1.* | sort -nt. | sed '$d' |  while read line; do rm -rf "$line"; done


oh yar thanks for pointing out the syntax part Smilie

You could combine like so for instance:
Code:
ls | egrep -v "Current$|$(ls -l Current | awk '{print $NF}')$"

The $ character is important to make sure that the patterns the grep matches are at the end of the line.

The Current$ does not work for me as I used a alias to do a
Code:
ls -F

Code:
leion > ls -ltr
total 0
   0 lrwxrwxrwx   1 leion  group         8 Jun 28 17:33 Current -> 1.0.0.12
   0 -rw-r--r--   1 leion  group         0 Jun 28 17:33 1.0.0.13a
   0 -rw-r--r--   1 leion  group         0 Jun 28 17:33 1.0.0.13
   0 -rw-r--r--   1 leion  group         0 Jun 28 17:33 1.0.0.12
   0 -rw-r--r--   1 leion  group         0 Jun 28 17:33 1.0.0.11
leion > ls | egrep -v "Current$|$(ls -l Current | awk '{print $NF}')$"
1.0.0.11
1.0.0.13
1.0.0.13a
Current@
leion > ls | egrep -v "Current|$(ls -l Current | awk '{print $NF}')$"
1.0.0.11
1.0.0.13
1.0.0.13a

However the combine of my twin grep -v using egrep -v helps.
Thank you for sharing. Smilie

Hi, you're welcome...
To temporarily bypass an alias you can use a backslash:
Code:
\ls | egrep -v "Current$|$(ls -l Current | awk '{print $NF}')$"
