Hi I've been searching google and have not found what egrep -c means. Does anyone know where I can get a cheat sheet or what that -c means?
thanks,

SYSTEMD-TMPFILES(8) systemd-tmpfiles SYSTEMD-TMPFILES(8)NAME
systemd-tmpfiles, systemd-tmpfiles-setup.service, systemd-tmpfiles-setup-dev.service, systemd-tmpfiles-clean.service, systemd-tmpfiles-
clean.timer - Creates, deletes and cleans up volatile and temporary files and directories
SYNOPSIS
systemd-tmpfiles [OPTIONS...] [CONFIGFILE...]
systemd-tmpfiles-setup.service
systemd-tmpfiles-setup-dev.service
systemd-tmpfiles-clean.service
systemd-tmpfiles-clean.timer
DESCRIPTION
systemd-tmpfiles creates, deletes, and cleans up volatile and temporary files and directories, based on the configuration file format and
location specified in tmpfiles.d(5).
If invoked with no arguments, it applies all directives from all configuration files. If one or more filenames are passed on the command
line, only the directives in these files are applied. If only the basename of a configuration file is specified, all configuration
directories as specified in tmpfiles.d(5) are searched for a matching file.
OPTIONS
The following options are understood:
--create
If this option is passed, all files and directories marked with f, F, w, d, D, p, L, c, b, m in the configuration files are created or
written to. Files and directories marked with z, Z, m have their ownership, access mode and security labels set.
--clean
If this option is passed, all files and directories with an age parameter configured will be cleaned up.
--remove
If this option is passed, all files and directories marked with r, R in the configuration files are removed.
--boot
Also execute lines with an exclamation mark.
--prefix=PATH
Only apply rules that apply to paths with the specified prefix. This option can be specified multiple times.
--exclude-prefix=PATH
Ignore rules that apply to paths with the specified prefix. This option can be specified multiple times.
--help
Prints a short help text and exits.
It is possible to combine --create, --clean, and --remove in one invocation. For example, during boot the following command line is
executed to ensure that all temporary and volatile directories are removed and created according to the configuration file:
systemd-tmpfiles --remove --create
EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise.
