# /etc/security/limits.conf

#Each line describes a limit for a user in the form:

#<domain> <type> <item> <value>

#Where:

#<domain> can be:

# - an user name

# - a group name, with @group syntax

# - the wildcard *, for default entry

# - the wildcard %, can be also used with %group syntax,

# for maxlogin limit

#<type> can have the two values:

# - "soft" for enforcing the soft limits

# - "hard" for enforcing hard limits

#<item> can be one of the following:

# - core - limits the core file size (KB)

# - data - max data size (KB)

# - fsize - maximum filesize (KB)

# - memlock - max locked-in-memory address space (KB)
