Delete Last part
Hello,

I am on solaris (ksh). I have a log file like this with directory structure and file name :

Code:
/DIR1/DIR2/DIR3/filename
/DIR1/DIR2/filename
/DIR1/DIR2/DIR3/DIR4/DIR5/filename

I am looking for a way to create a new file to be formated like this :

Code:
DIR2/DIR3
DIR2
DIR2/DIR3/DIR4/DIR5

The idea is to :
1 : get rid of the first directory name and the file name listed inside of the last directory in the log file

2 : and then to be able to create a loop in a shell script to re-create - on a different way - the directory sctructure on another disk.

Tanks in advance for your help

bash
Hi,

Try this one,

Code:
#! /usr/bin/bash
while read line
do
line=${line%\/*}
line=${line#\/*\/}
echo $line >>file.new
done <file

Look at the sed and awk solutions too Smilie

Code:
awk '{gsub(/\/[^/]*$|^\/[^/]*/,"");}1' file >newfile
sed 's/\/[^/]*$//;s/^\/[^/]*//g' file>newfile

Cheers,
RangaSmilie

A sed one:
Code:
$ sed "s|/[^/]*/\(.*\)/.*|\1|" file
DIR2/DIR3
DIR2
DIR2/DIR3/DIR4/DIR5

Thank you so much for your help .... You were so fast

Dear Rangarasan,

your command

Code:
awk '{gsub(/\/[^/]*$|^\/[^/]*/,"");}1'

gives me error :

Code:
awk: syntax error near line 1
awk: illegal statement near line 1
awk: syntax error near line 1
awk: bailing out near line 1

maybe it's because I am on ksh, but I did try with "nawk" but no success ... Thanks anyway for your help


Thanks In2nix4life, but you code give no change ... strange ...
