How can I use the value of an argument as a filename? Example:
The argument for a process is 999. I would like the output of the process to be placed in a file called 999. I have tried using $$1, but that only assigns a unigue number.
thanks

touch
TOUCH(3) 1 TOUCH(3)touch - Sets access and modification time of fileSYNOPSIS
bool touch (string $filename, [int $time = time()], [int $atime])
DESCRIPTION
Attempts to set the access and modification times of the file named in the $filename parameter to the value given in $time. Note that the
access time is always modified, regardless of the number of parameters.
If the file does not exist, it will be created.
PARAMETERS
o $filename
- The name of the file being touched.
o $time
- The touch time. If $time is not supplied, the current system time is used.
o $atime
- If present, the access time of the given filename is set to the value of $atime. Otherwise, it is set to the value passed to the
$time parameter. If neither are present, the current system time is used.
