Changes in the login shell from Jaguar to Panther
A reader from Austria writes:
As I'm now working through your book Learning Unix for Mac OS X Jaguar, I can't get the commands "alias" and "grep" to work. Has been there a change in the command definition from Jaguar to Panther? alias ls='ls -F'In terms of grep not working, that shouldn't be an issue. Is it in your PATH? That is, if you type: which grepDoes it find the command? One of the more controversial changes in the Jaguar to Panther update was this transition from tcsh to bash, but I have to say that I'm a big fan of the Bash shell, so for me, it was a good transition. Remember also that if you want to stick with the tcsh shell, you can simply change you default shell setting in the Terminal.app application. Go to Terminal -> Preferences and specify a different shell with "Execute this command (specify complete path)" by entering /bin/tcsh and ensuring that the second option is selected, not the default.
