I was trying to test the presence of some files on Red hat Linux enterprise version 2.4.9 using the following command
test -f /home/pv/T20*
I am getting the error, too many parameters, when I have multiple files starting with T20 on that directory. When there is no files or just one file, no errors and the command works.
Any idea whay I can't check the presence of multiple files? Or is there any other command I can use for this purpose.
I just want to see(by a a single commad) if there is any file starting with those letters present in that directory so that I can do some processing on those files. test -f /home/pv/T20* command works perfect on HP-UX and I assume it is a bug on this flavor of Linux.
Another way to test for files
However, this would return true for directories and empty files. Since you want to do some processing on the files why not use a for loop...
If there are no files then the code within the for loop is not executed and this message is sent to standard error: "/home/pv/T20* not found"
PS: It is not good practice to rely on "if test -f" for multiple files. Here's why (on HP-UX)....
$ ls *.txt
b.txt c.txt
$ if test -f *.txt
> then
> echo true
> else
> echo false
> fi
true
$ mkdir a.txt
$ if test -f *.txt
> then
> echo true
> else
> echo false
> fi
false

This is the code:

if test $a = stop

done
I read a command on every loop an execute it.
I check if the string equals the word stop to end the loop,but it say that I gave too many arguments to test.
For example echo hello.
