What Linux Administration Commands does

A legacy Linux command reference with DirSkills safety notes for emergency reboot, memory, I/O, background jobs, and older GRUB configurations.

Linux Administration Commands is cataloged under DevOps on DirSkills.

DirSkills review

This is a legacy quick-reference document, not a safe modern administration runbook. Several commands are destructive or distribution-specific.

  • Writing b to /proc/sysrq-trigger reboots the host without a normal shutdown; never run it on production without an approved emergency procedure.
  • The /etc/grub.conf example targets older Red Hat-era layouts. Current distributions generally use GRUB 2 tooling, so verify the operating system documentation first.

Documentation

README

1 远程重启计算机

echo b > /proc/sysrq-trigger

2 查看内存使用情况

free -m //以MB为单位查看内存使用情况

3 修改计算机的可用内存

对于Redhat系(包括Fedora)

修改/etc/grub.conf，在kernel一行最后添加mem=1G就能够将可用内存修改为1GB

title Red Hat Enterprise Linux Server (2.6.27)
        root (hd0,1)
        kernel /vmlinuz-2.6.27 ro root=/dev/VolGroup00/LogVol00 rhgb quiet acpi=ht mem=1G
        initrd /initrd-2.6.27.img

4 查看系统的IO统计信息

iostat -k 3 //以KB打印结果，3秒显示一次

5 将一个进程放入后台，并使它不受前台的影响，特别是用于远程连接时

./test //运行程序
^Z //ctrl+z使程序暂停
bg %(jobid) //将程序放入后台运行
disown -h %(jobid)
