Make locate command availableThe find command is often used to search for specific files throughout the Linux system, but find is somewhat confusing in terms of specifying options.The locate command can extract all files with a specified filename.4. vim editor settingsUbuntu has vim installed by default4.1 Change vim settingsThere may be cases where you do not want to allow vim settings for all users. In such cases, a ".vimrc" file can be created in each user's home directory to change the vim environment for each user.In this case, we will create a ".vimrc" file in the root user's home directory "/root/" and apply it to all users.

FreeBSD14.1 : Jail Install

JailIt is a mechanism that allows multiple virtual FreeBSD environments to be created on a FreeBSD environment.A jail is an extension of chroot, and a jail environment (called a prisoners) built on a host ring (called a jailer) behaves as a FreeBSD machine running separately from the host environment.The prisoner cannot directly attach to the jailer or another parallel prisoner.Features of JAIL・High speed operation because it is not emulation.・Each prisoner can be assigned an IP address different from that of the jailer.・Since the same file system is used for a jailer and a prisoner, it is necessary to be careful about the assignment of UID/GID.This time, build two prisoners (prisoner1 and prisoner2) in jailer (FreeBSD14.1)
