exec:tldr:02160
The command exec -a ${process_name} ${command -with -flags}
is used to execute another command and optionally assigns a custom name to the process.
Here's a breakdown of the command:
-
exec
: This is a built-in command in Unix-like operating systems that replaces the current process with a new process. It allows you to execute a command from within a shell script or the command line. -
-a ${process_name}
: This option in theexec
command assigns a custom name to the process being executed.${process_name}
is a placeholder for the name you want to assign. It can be any valid string without spaces. -
${command -with -flags}
: This is the command you want to execute, along with any flags or options that it requires.${command -with -flags}
is also a placeholder for the actual command you intend to run, along with any necessary flags or options.
By using this exec
command, the specified ${command -with -flags}
will be executed with the given process name ${process_name}
. The original shell or script that invoked the exec
command will be replaced by the new process. This can be useful when you want to run another command but still keep the same process ID and other information associated with the parent process.
