Can I setup multiple commands on a single alias.
For example, I want to have one alias that changes the directory, and launches an executable with specific parameters.

How can I do that, and what are the syntax for it?

alias mcd='cd /devt/vbs/ncr' 'ct co -nc'

alias mcd='cd /devt/vbs/ncr;ct co -nc'
alias mcd='cd /devt/vbs/ncr && ct co -nc'
the && makes sure the first command returns without an error before trying the second, the first just runs them one after other

In this case you could also do:

alias mcd="(cd /devt/vbs/ncr; ct co -nc)"

That will execute the change dir & command in a subshell which won't change the current working directory.

Hi Axter,

yes you can
alias mcd='cd /devt/vbs/ncr && ct co -nc'

second will be executed only if first is successful

One other thing to be careful with.  The use of " or ' makes a BIG difference with
command substitution in your shell.  " allows variable substitution, ' does not.
