exec: Linux Commands HowTo
exec: Execute a command
Execute a command
Syntax
exec [-cl] [-a name] [command [arguments]]
Options
-l Place a dash at the beginning of the zeroth arg passed to command.
(This is what the login program does.)
-c Causes command to be executed with an empty environment.
-a The shell passes name as the zeroth argument to command.
If command is supplied, it replaces the shell without
creating a new process. If no command is specified, redirections
may be used to affect the current shell environment.
If there are no redirection errors, the return status is zero; otherwise the
return status is non-zero.
exec is a BOURNE shell command and a POSIX `special? builtin
To execute a shell script from the command line, prefix the script?s name with ./
./myscript
You may be tempted to fix this by adding ?.? to your $PATH but this is widely considered to be a bad idea (for security reasons).
If you want to execute something in the current directory, just type
the "./" in front of the command name.
"In art the hand can never execute anything higher than the heart can inspire" - Ralph Waldo Emerson
