[mngshm]

can you elaborate the issue ? and sorry for the late reply

[polluks]

My Buster has no option m pgrep from procps-ng 3.3.15

[mngshm]

try updating the procps-ng package

[polluks]

well...

$ sudo apt upgrade procps
Reading package lists... Done
Building dependency tree
Reading state information... Done
procps is already the newest version (2:3.3.15-2).
Calculating upgrade... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

so I have to use unstable software?

[mngshm]

I have no idea cuz debian based distros are the only ones which are getting weird issues

[proffapt]

can fix this by using ps and then grep'ing it's output, non-suggested method.. but works since pgrep in macos (BSD version) has this same issue.

@Mangeshrex I'm using arch and pgrep doesn't support neither -m nor -e options, are you sure that the version of pgrep that you're using supports those options?
