Network Single to multiple line file

Code:
echo 'a^Mb^M' | tr '\r' '\n'

'^M' is a single character.

what is a and b

this is just a hint at a solution.

ctrl/M is carriage-return not line-feed.
Was this file created as a text file on a M$ platform?
Does it just need converting to unix text file format with "dos2ux" or "dos2unix" depending on what unix you have?

sorry

both tr and

dos2unix
not working

my i/p is like this
bikwenbl^Mbikwenbl^Mbikwenbl^M (single line)

o/p file should be like this
bikwenbl^M
bikwenbl^M
bikwenbl^M (3 lines)

thanks DAPTAL
you have already given the sol. very simple

awk -F '|' '{for(i=2;i<=NF;i++){ print $1.$i}}' filename

works very well even take ^M as delimiter


thanks all

I have posted the fully correct "tr" command on your other thread.

Can't see the relevance of the "awk" example posted in this context.

What "awk" script did you actually use which worked?


The "dos2unix" command syntax posted in response to yet another of your threads is incorrect.

Now you know the command name, you can look it up in the unix manual pages yourself.
