>Usage
The pgrep command in Unix is used to search for processes currently running on the system based on specified criteria, such as process name, user, or group. It outputs the process IDs of matching processes.
>Synopsis
pgrep [-u | -l | -f | -c ...]
>Options
-u
Lists process IDs for processes owned by a specified user.
Example:
-zsh
> pgrep -u john
1032
2048
-l
Displays the process ID and the name of each matching process.
Example:
-zsh
> pgrep -l python
1032 python3
2048 python2
-f
Matches against the full command line rather than just the process name.
Example:
-zsh
> pgrep -f my_script.py
1032
-c
Counts the number of matching processes.
Note: This option is not supported on macOS; it is only valid on Linux.
Example:
-zsh
> pgrep -c python
