mind bash
Alalush ,
- using escape sequences (eg. "\t") on shell strings works uniformly among most shells in the unix world (sh - the bourne shell , and ksh - korn shell) ;
- however, this is not true for linux and bash (bourne again shell) ;
-- in bash, you must use the "-e" flag on echo , in order to produce the same effect for the escape sequences ;
hope this helps.
good luck , and success !

Hi All,
I'm trying to use the "echo" command in a korn shell script, and I want it to drop the trailing newline. Now I know that with the bash shell, the "-n" flag would solve this issue. Does anyone know how this can be done with the korn shell?
Cheers

I am learning to build from SVN and other tools, with a lot of copying and pasting from forums. I like to append && echo "success" to all commands so that I can see at a glance if things went all right. Is there a way that I can have the bash shell append this to all commands?
Thanks! (5 Replies)
