[8:35pm] cat t
12 34 56
[8:36pm] cut -d " " -f1 t ; cut -d " " -f2 t ; cut -d " " -f3 t

可以写一个script来偷懒：
# shell script to replace space with new line
#!/bin/sh
echo -n "Enter the input file name: "
read input
cut -d " " -f1 $input; cut -d " " -f2 $input; cut -d " " -f3 $input
以下为运行结果：
[8:44pm] sh xixi
Enter the input file name: t

发帖数: 179 | 3 Let's do a test in explicit shell definition.
[12:04am] tail -n 1 ~/.cshrc
alias prsth 'echo "It Works"'
[12:04am] cat xixi.csh
#!/bin/csh
prsth
[12:04am] ./xixi.csh
It Works
[12:04am] cat xixi.sh
#!/bin/sh
prsth
[12:04am] ./xixi.sh
./xixi.sh: prsth: not found
Isn't it clear now? |
