This is because those characters are used in the names of special Unix variables. These variables are reserved for specific functions. For example, the  $  character represents the process ID number, or PID, of the current shell − $echo $$ The above command writes the PID of the current shell − 29949 The following table shows a number of special variables that you can use in your shell scripts − Command-Line Arguments The command-line arguments $1, $2, $3, ...$9 are positional parameters, with $0 pointing to the actual command, program, shell script, or function and $1, $2, $3, ...$9 as the arguments to the command. Following script uses various special variables related to the command line − #!/bin/sh echo "File Name: $0" echo "First Parameter : $1" echo "Second Parameter :...
