UNIX for Dummies Questions & Answers

I have defined this alias as quick way to find out which mount point to use for a USB drive after inserting it:

Code:

# alias da='dmesg | grep da | grep MB'

However, when invoking it, it states the following:

Code:

# da
da: Command not found.

Can someone explain what is the issue here and how it can be resolved?

What is your shell?

Given FreeBSD and the # prompt which I take to be that you were logged in as root, Im assuming that you're running under csh/tcsh (the shell assigned to root by default when you install FreeBSD).

I was able to reproduce the problem, but only under FreeBSD (bugger is the host name)

Code:

bugger# alias foo="echo bar"
bugger# foo
foo: Command not found.
bugger# csh --version
tcsh 6.14.00 (Astron) 2005-03-25 (i386-intel-FreeBSD) options wide,nls,dl,al,kan,rh,color,filec

When I try this with csh on a linux host it works fine. The version on linux is more recent, so this could just be a csh bug. I don't use csh, so unfortunately the only things I can offer are:

1) switch the login shell for root in /etc/password to ksh or bash.

2) check the version of csh on your host, and if its out of date with the FreeBSD ports collection upgrade it. No assurance that an upgrade will fix it, but it'd be worth the try if you want/need to use csh over ksh.

The version on my linux host is:
tcsh 6.15.00 (Astron) 2007-03-03 (i586-suse-linux) options wide,nls,lf,dl,al,kan,sm,color,filec

Hope this was of some use.

SOLVED:
The equal sign (=) should be removed. The command now is:

Code:

alias da 'dmesg | grep da | grep MB'
