gNU Bourne-Again SHell (GNU Bourne-Again SHell)
Аргументы (Arguments)
If arguments remain after option processing, and neither the -c
nor the -s option has been supplied, the first argument is
assumed to be the name of a file containing shell commands. If
bash is invoked in this fashion, $0 is set to the name of the
file, and the positional parameters are set to the remaining
arguments. Bash reads and executes commands from this file, then
exits. Bash's exit status is the exit status of the last command
executed in the script. If no commands are executed, the exit
status is 0. An attempt is first made to open the file in the
current directory, and, if no file is found, then the shell
searches the directories in PATH for the script.
