标题: 两个linux命令

今天学到了两个命令，其实都很简单，只是自己很少使用而不知道罢了，这里简单记录一下
tar
几乎天天都会用到，今天却遇到一个新问题，如何将指定的一些目录不打到包内？操作如下：
tar -cvf target.tar --exclude=目录1 --exlude=目录2.。。。。。源目录
script
这个命令用来将操作的过程保存在日志中，securecrt中有设置log的功能，没想到操作系统上也可以，语法和使用都很简单：
语法：script [-a] [-f] [-q] [-t] [file]
1、执行script命令
[mysql@bj122 mysql]$ script
Script started, file is typescript
2、随便执行一些命令
[mysql@bj122 mysql]$ ls
charge_2008             checklog       dbalert.tar mysql                                  pointcard_slave.tar.gz
charge_alert             checklog.tar    etl_daily    MysqlAlert.class                         temp
charge_alert.tar          checklog.tar.gz  etl_daily.tar  mysql_db.tar                            ttt.txt
charge_stat_for_yuhui    cron_mysql    ftptst.ctl    mysql-standard-5.0.27-linux-i686-glibc23  typescript
charge_stat_for_yuhui.tar  dbalert       ip.txt       nohup.out
[mysql@bj122 mysql]$ w
17:34:09  up  7:40,  5 users,  load average: 0.01, 0.02, 0.00
USER    TTY    FROM             LOGIN@ IDLE JCPU PCPU  WHAT
search pts/0 203.86.63.98    9:56am  1:39 0.41s  0.04s  -bash
zxzhai pts/2 203.86.63.98    11:37am  0.00s  0.42s  0.11s  -bash
zxzhai pts/3 203.86.63.98    11:46am  1:58m  0.15s  0.03s  ssh -p7522 192.168.160.32 -lzzx
search pts/4 203.86.63.98    11:57am  3:03m  0.12s  0.03s  -bash
search pts/5 203.86.63.98    2:13pm  3:19m  0.20s  0.04s  -bash
3、退出script
[mysql@bj122 mysql]$ exit
exit
Script done, file is typescript
4、日志记录在typescript文件中
[mysql@bj122 mysql]$ more typescript
Script started on Wed Jul  2 17:34:03 2008
[mysql@bj122 mysql]$ ls
charge_2008             checklog       dbalert.tar mysql
            pointcard_slave.tar.gz
charge_alert             checklog.tar    etl_daily    MysqlAlert.class
      temp
charge_alert.tar          checklog.tar.gz  etl_daily.tar  mysql_db.tar
         ttt.txt
charge_stat_for_yuhui    cron_mysql    ftptst.ctl    mysql-standard-5.0.27-linux-i686-glibc2
3  typescript
charge_stat_for_yuhui.tar  dbalert       ip.txt       nohup.out
