Hi pravin... does not work...
what shall i use as delimiter?

tried "" and "\n"

So your command gives following error:
Code:
paste: no delimiters

and mine works with \n but i can't see any difference.... lines are still not concat. to 1 line and single string wasn't removed

Lets try with:
Code:
echo "abc/de/fg/
12/3/4/5/67/
morestuff/" | sed 's/\/$//' | tr -d "\n"
abc/de/fg12/3/4/5/67morestuff

Let's try with perl.
Code:
perl -ne 'chop $_;printf $_; END {printf "\n";}' input.txt

@suresh.boddepu works well thx / for noobs like me ;-) i checked manpage:
ORS output record separator (default new-line)
@pravin27 does not remove the / at line ending - but thx for try... just need to add this removal
@cgkmal nice... can you please tell me how this command would look like with input and output file?

Thanks a lot!

This works fine:

Code:
sed 's/\/$//g' inputfile | awk '{ORS="";print}' > outputfile

I don't understand the full requirements. Are we guaranteed that we have exactly 3 lines. Or are we guaranteed that we have a multiple of 3 lines and every 3 lines should be combined into a single line. Assuming one of these is true....
Code:
$
$ cat inputfile
abc/de/fg/
12/3/4/5/67/
morestuff/
zxy/xx/kk/
99/8/7/9/9999/
evenmorestuff/
$ sed -n 'N;N;s=/\n==g;s=/$==;p' inputfile
abc/de/fg12/3/4/5/67morestuff
zxy/xx/kk99/8/7/9/9999evenmorestuff
$

I cut and pasted this from a terminal window to a Solaris system where I tested it. This works on Solaris 10.

Hi unknown7,

Sure!. It would be like this:
Code:
sed 's/\/$//' inputfile | tr -d "\n" 
abc/de/fg12/3/4/5/67morestuff

or
Code:
sed 's/\/$//' inputfile | tr -d "\n" > outputfile

cat outputfile
abc/de/fg12/3/4/5/67morestuff

Best regards
