Can not remove file using rm command
I have two questions:

the first is I have a line of code:

Code:
 printf "What is the id of the patient getting GJB2 analysis  : "; read id

that stores a user input in a variable $id in the python directory c:/Users/cmccabe/Desktop/Python27/$id.txt

Using rm I get the error cannot remove $id.txt no such file. The exact command is:

Code:
 
cd 'C:'
rm  c:/Users/cmccabe/Desktop/Python27/${id}.txt

I have also tried

Code:
 
cd 'C:'
rm  c:/Users/cmccabe/Desktop/Python27/"${id}".txt

I will post the second question in a different theard. Thank you Smilie

  1. what's the value of ${id} variable?
  2. If id=foo, does the file c:/Users/cmccabe/Desktop/Python27/foo.txt exist?

what is "cd c:"?

The value of ${id}.txt is snp, so snp.txt is the value and I see that in the python directory and can manually delete it, but using rm I can not. Thank you Smilie

Python is in a windows directory so I do cd to c:/.

usually it has to do with the path and/or the file name being correct or permissions.
Add set -x to your shell script and see what shell script is trying to do.
Good luck.

may be you should try del instead of rm? ;-)

For some reason the value for the ${id} variable, in this case snp, isn't getting passed. I'm not sure why but in other functions I use the variable. Thank you Smilie
