Subject: [PATCH 1/2] python-linux-procfs: pflags: Use argparse to create a |
||||
help option |
||||
|
||||
The purpose of this change is to create a -h or --help option. |
||||
In addition the handling of pids or process names is improved. Instead of a |
||||
command separated list (without spaces), the more standard unix way of |
||||
space separated command line arguments are used. |
||||
|
||||
This is explained in the help. |
||||
|
||||
./pflags -h |
||||
usage: pflags [-h] [pid [pid ...]] |
||||
|
||||
Print process flags |
||||
|
||||
positional arguments: |
||||
pid a list of pids or names |
||||
|
||||
optional arguments: |
||||
-h, --help show this help message and exit |

Subject: [PATCH 2/2] python-linux-procfs: pflags: Ignore non-existent pids or |
||||
process names |
||||
|
||||
If the user enters a non-existent pid or process name, skip over it. |
||||
|
||||
Also, if the user enters nothing but a non-existent pid, then don't |
||||
calculte max_comm_len since you can't take the max of an empty list. |
