Error writing to a file
Hi All.

I have the following simple shell program.

It reads a number from the "/user/amit/bldno";

for example: file "bldno" contains value "100"

After execution of the program the content should change to 101.

---------
#!/usr/bin/tcsh
V= `cat /user/amit/bldno`
echo $V
`rm -rf /user/amit/bldno`
NV = expr $V + 1
echo $NV > /user/amit/bldno
---------------------

It is not writing new value to file "/user/amit/bldn

Could pls help.

Thanks

Amit
