Remove ^M (CR) from Unix Files
Is there any way we could remove the "^M" from files on unix?

and also what is the best way to count the TABS in a TAB delimited file per record?

Thanks,
AC

You can try also :
cat file1 | tr -d "\r" > file2

Is cat needed?

Code:
tr -d "\r" <file1 >file2

Code:
strings file_name > file_name_without_control_chars

sed 's/^M$//' <file> > <newfile>

( "^M" has to be entered as CTRL-M)

Alternative possibilities include "dos2unix" and similar programs.

Nearly every program is able to remove trailing LF-characters it seems. ;-))

You have to use dos2unix (linux) or dos2ux (hp-ux) for this. Encoding is getting different from dos to unix with ^M character.
