hello, i am trying to put users2 information to file appraisalrecord, however it is not working and i tried everything. overall, i just want to show that when they enter the user number it will verify in the file to see does that user number exist, if yes they have to a new user number if no they continue on and the user number is put in the appraisalrecord. hope you understand what im saying. im using UNIX shell as well.
"what kind of shell are you using?" "unix"
"what kind of car are you driving?" "blue"
UNIX has many shells, "UNIX shell" tells us nothing.
If you're not using BASH, read -p won't work or won't do what you expect -- -p means read from a coprocess in ksh for instance, and other shells won't have it at all.
What's in appraisalrecord?
This is to remove everything except digits I take it?
Why is newrecord calling itself? This will be a recursion. And the existing call to newrecord won't end, potentially making it an infinite recursion. You should have a loop outside newrecord that keeps calling it in a loop if you want it to happen more than once.
Instead of checking the output of grep, why not check grep's return value? it returns nonzero when nothing's found, and zero when it's found, so:
This will blow up whenever users2 or output1 are blank, put quotes around them.
