Tcsh: Append output to a file

Tcsh: Append output to a file

[Axel H. Siebenwirth]

Hello!

For example I use "/usr/local/sbin/dsniff >& dsniff.log &" in a start-up
skript to log the output to a file. But everytime I start my computer a new
file "dsniff.log" is created.

My question is: How do I append to an existing file?


Thank you,
Axel Siebenwirth

/usr/local/sbin/dsniff >>& dsniff.log &

The double >> is the "append" instruction.

Okay. First off, thank you!
I confused myself. Shell chaos. I'm using tcsh as all my login shells. But
the startup scripts are all bash scripts. So I really asked my self why what
you told me works on command line but not from the script.

Can you please tell me how to the same thing for bash? :)

Thank you,

First off, you don't _have_ to use bash for scripts.  Instead of
starting the script #!/bin/[ba]sh, it can start #!/bin/tcsh.

If you want to use bash, this should do it:

Script started on Tue May 14 22:38:27 2002
[whit@giftie whit]$ echo $SHELL >file 2>&1
[whit@giftie whit]$ echo $SHELL $SHELL >>file 2>&1
[whit@giftie whit]$ cat file
/bin/bash
/bin/bash /bin/bash
[whit@giftie whit]$ exit

Script done on Tue May 14 22:39:30 2002

/usr/local/sbin/dsniff >> dsniff.log &

if you just want output in the file,

/usr/local/sbin/dsniff >> dsniff.log 2>&1 &

if you want output and errors.
