shell處理文本可能沒有perl強大，但是在一些特殊用途下也是很出色的，廢話少說，直接看如下實例:
[www.linuxidc.com @linux source]$cat sinadept.txt
Harry Potter:100:Magic School
Alex Jason:200:Sales
Yu Chao:300:SINA Product Development
Sanjay Gupta:400:Support
Nisha Singh:500:Sales
Yu Jun:1000:Peking University EECS
[www.linuxidc.com @linux source]$cat sinastaff.sh
#!/bin/sh
#[email protected]
IFS=:
echo "Employee Names:"
echo "---------------"
while read name empid dept
do
echo "$name is part of $dept department"
done < ~/source/sinadept.txt
[www.linuxidc.com @linux source]$sh sinastaff.sh
Employee Names:
---------------
Harry Potter is part of Magic School department
Alex Jason is part of Sales department
Yu Chao is part of SINA Product Development department
Sanjay Gupta is part of Support department
Nisha Singh is part of Sales department
Yu Jun is part of Peking University EECS department
[www.linuxidc.com @linux source]$
可以看到，根據我們特地的要求輸出了確定的值了。
