Multiple entries for shell
I have a simple shell file (convert.sh), that I would like to add a loop to that allows the user to have the "Enter ID:" prompt keep displaying until end is typed.

So instead of:
Code:
bash ~/convert.sh
Enter ID:123
bash ~/convert.sh
Enter ID:456
bash ~/convert.sh
Enter ID:789

The user would enter
Code:
bash ~/covert.sh
Enter ID:123
Next ID: 456
Next ID:789
Next ID:end (shell exits)

Thank you Smilie.

Code:
 #!/bin/bash
echo -n "Enter ID  : "; read id
perl convert2annovar.pl -includeinfo -format vcf4old ${id}_matched.vcf > ${id}_matched.avinput

"echo -n" is not portable, but "printf" works the same everywhere.

Code:
while true
do
        printf "Enter ID  : " ; read id
        [ -z "$id" ] && break
        [ "$id" = "end" ] && break
        perl convert2annovar.pl -includeinfo -format vcf4old ${id}_matched.vcf > ${id}_matched.avinput
done

I apologize for forgetting all the code tags.

---------- Post updated at 10:20 AM ---------- Previous update was at 10:14 AM ----------

Code:
 [ "$id" = "end" ] && break

is it possible to exit cygwin if end is typed? Thanks.

Explain the difference between exiting the script and exiting cygwin, please.

If you mean "close the terminal", I wouldn't expect the terminal to stick around unless it was expecting user input -- i.e. was an interactive shell. In which case your script was ran incorrectly, rather than it quitting incorrectly.

How are you running your script?

exiting the script the terminal stays open, exiting cygwin the terminal closes.

I change directories and run:
Code:
 bash ~/convert.sh

I enter id's until there are no more then type end and the terminal stays open. Thanks Smilie.

If you ran it from a batch file by double clicking it, I think it would close. Otherwise, that's beyond cygwin's control unless you start fiddling with blunt and impolite things like kill (which would only work questionably well with pure Windows things anyway).
