请问如何替换文件内容

发表于:2007-07-04来源:作者:点击数: 标签:
awk 'BEGIN { i = 100 } = "tty"i++ ' filename

一个文件内容如下:
61a:23:off:/etc/getty tty61a m
61b:23:off:/etc/getty tty61b m
61c:23:off:/etc/getty tty61c m
61d:23:off:/etc/getty tty61d m
61e:23:off:/etc/getty tty61e m
61f:23:off:/etc/getty tty61f m
61g:23:off:/etc/getty tty61g m
61h:23:off:/etc/getty tty61h m


请问下如何用shell将tty61a改为tty100,
                           tty61b改为tty101,
                  tty61c改为tty102,
                      。。。。。。。。。。
                 tty61h改为tty108.


方法1:
awk 'BEGIN { i = 100 } = "tty"i++ ' filename
