Operating Systems HP-UX Script execution is very slow when trying to find all files and their owners on HP-UX box Post 302952193 by Corona688 on Friday 14th of August 2015 04:24:35 PM

What you are doing is known as "thrashing the disk", the sort of thing you're only supposed to do late at night when interactive users aren't around to experience the lagging. (i.e. how the locate database is updated).

Walking every single directory to call stat on every single individual file is never going to be fast, period. Your implementation is far from efficient but I don't think there's much improvement to be had since the wall you're hitting is your disk speed.

CGCONFIGPARSER(8)						 libcgroup Manual						 CGCONFIGPARSER(8)

NAME
cgconfigparser - setup control group file system SYNOPSIS
cgconfigparser [-h] [-l <filename>] [-L <directory>] [...] OPTIONS
-h, --help Displays help. -l, --load=FILE Parses the control groups configuration file Sets up the control group file system defined by the configuration file and mounts mount points defined by the configuration file. The format of the file is described in cgconfig.conf. This option can be used mul- tiple times and can be mixed with -L option. -L, --load-directory=DIR Finds all files in given directory and parses them in alphabetical order like they were specified by -l option. This option can be used multiple times and can be mixed with -l option. -a <agid>:<auid> defines the default owner of the rest of the defined control group's files. These users are allowed to set subsystem parameters and create subgroups. The default value is the same as has the parent cgroup. -d, --dperm=mode sets the default permissions of a control groups directory. The permissions needs to be specified as octal numbers e.g. -d 775. -f, --fperm=mode sets the default permissions of the control group files. The permissions needs to be specified as octal numbers e.g. -f 775. The value is not used as given because the current owner's permissions are used as an umask (so 777 will set group and others permis- sions to the owners permissions). -s, --tperm=mode sets the default permissions of the control group tasks files. The permissions needs to be specified as octal numbers e.g. -f 775. The value is not used as given because the current owner's permissions are used as an umask (so 777 will set group and others per- missions to the owners permissions). -t <tuid>:<tgid> defines the default owner of tasks file of the defined control group. I.e. this user and members of this group have write access to the file. SEE ALSO
