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.

Laptop Hardware

[Dan Bentson-Royal]

I am about to purchase a new laptop. Is there a place where I can find caveats
about what hardware is going to be trouble free? I am buying a MITAC
laptop and want to make sure that I don't have some bizarre problem with
the video chipset or other. I'll go with a RedHat install.

Thanks for anything you can suggest!

I have no idea if there is even a URL for this, however you mentioned video, 
now that is the most important, i suggest you ask the shop keeper what video 
set it has and check it out at http://xfree86.org
Even tho' i have never heard of that make of laptop i doubt if you will have 
any problems at all as redhat is very good with laptops.

O yes, one problem with may occur is a standard 56K tel modem, most laptops 
have a lucent chip modem, that in itself is no problem as it can be gotten to 
work under linux.

You might check http://www.notebookreview.com/ and look for any links 
about hardware.
