想要使文本以整齐的tab表示，可以使用column -t命令

例子：

[mysqld_multi]
mysqld = /usr/local/mysql/bin/mysqld_safe
mysqladmin = /usr/local/mysql/bin/mysqladmin
user = root
log = /var/log/mysqld_multi.log

[mysqld3306]
port = 3306
socket = /tmp/mysql3306.sock
pid-file = /var/run/mysql/mysql3306.pid
datadir = /data/innodb
user = mysql

写入到my.test.cnf中

运行

column -t my.test.cnf

变成了

[mysqld_multi]
mysqld          =  /usr/local/mysql/bin/mysqld_safe
mysqladmin      =  /usr/local/mysql/bin/mysqladmin
user            =  root
log             =  /var/log/mysqld_multi.log
[mysqld3306]
port            =  3306
socket          =  /tmp/mysql3306.sock
pid-file        =  /var/run/mysql/mysql3306.pid
datadir         =  /data/innodb
user            =  mysql
