New to scripting and adding aliases, and have this exercise with RHA, wondering if anyone could help


Edit your ~/.bashrc file, so that newly started bash shells have the following properties.

1. The alias dir executes the command ls -l.
2. The alias globoff disables pathname expansion (by enabling the appropriate shell flag).
3. The complimentary alias globon enables pathname expansion (by disabling the appropriate shell flag).
4. When redirecting output to a file, the bash shell will not clobber (overwrite) an already existing file.
5. The shell has the cdspell shell option enabled.
6. The rm command is aliased to rm -i.

Challenge Exercise

The following exercise may be completed as a challenge exercise. It will not be graded by the automated grading script.

Configure the primary prompt to contain the history number and exit code of the previously executed command, separated by a : (with no spaces). The colon should be the only colon contained in the prompt.

If appropriately configured, the prompt should have behavior similar to the following. Note carefully the behavior of the prompt after a successful command, after an unsuccessful command, and as it relates to the history number of the previously executed command.

[madonna@station madonna] 40:0 $ ls -d /tmp
/tmp
[madonna@station madonna] 41:0 $ ls -d /TMP
ls: /TMP: No such file or directory
[madonna@station madonna] 42:1 $ history
...
41 ls -d /tmp
42 ls -d /TMP
43 history
[madonna@station madonna] 43:0 $ !42
ls -d /TMP
ls: /TMP: No such file or directory
[madonna@station madonna] 44:1 $

You're joking right? most people actually try to slightly hide the fact that it's homework.....

please do not ask for help with assignments here. you need to learn for yourself.

HAHA

Just hitting a brick wall right now with it, and that is why I came here for help..... It is part of learning... But as I understood you do not want me gathering information from this site?

LQ rules clearly state:
Your question is a homework one. In such cases we don't answer directly. You'll get only general guidelines.

I recommend you to look into Bash reference here: http://www.gnu.org/software/bash/manual/bashref.html
You can find ansers by simply searching for keywords like alias or pathname. The way the questions are written makes this really easy.

Thank you... It's nice to read other writing styles on the same topic... very usefull... Good day....
