Problem with path and child shells
Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!
1. The problem statement, all variables and given/known data:
a) Some Unix tools are at $HOME/mytools directory. Make these tools accessible for use from any directory.
b) Make these tools usable from child shells.
c) How to make them readily usable whenever you login to the UNIX shell.
2. Relevant commands, code, scripts, algorithms:
echo, PATH, bash
3. The attempts at a solution (include all code and scripts):
My attempt for a) is PATH=$PATH\: $HOME/mytools
b and c I have noo idea about.
I know what child shells are, but isn't the mytools already accessible by them? For c, does it want me to change the path to mytools??
4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):
University of Alabama at Birmingham, Birmingham (AL), US, Taofiq, cs333
do not have a link to class
Note: Without school/professor/course information, you will be banned if you post here! You must complete the entire template (not just parts of it).
