Yes -- but the command in the given string is "debian", which is not a 
valid command.

"./" is required when a command is in the current working directory and 
the current working directory is not in the PATH environment variable. 
"./" is not required for file arguments in the current working directory:

2024-09-01 01:11:28 dpchrist@laalaa ~
$ echo 'hello, world!' > hello.txt

2024-09-01 01:11:37 dpchrist@laalaa ~
$ echo 'cat $@' > foo

2024-09-01 01:11:43 dpchrist@laalaa ~
$ chmod +x foo

2024-09-01 01:11:48 dpchrist@laalaa ~
$ ./foo hello.txt
hello, world!
