交互式(Interactive):解释执行用户的命令,用户输入一条命令,Shell就解释执行一条。 批处理(Batch):用户事先写一个Shell脚本(Script),其中有很多条命令,让Shell一次把这些命令执行完,而不必一条一条地敲命令。 Shell脚本和编程语言很相似,也有变量和流程控制语句,但Shell脚本是解释执行的,不需要编译,Shell程序从脚本...

echo "Remaining arguments:" for arg do echo '--> '"\`$arg'" ; done 比如我们使用 ./test -a -b arg arg1 -c 你可以看到,命令行中多了个arg1参数,在经过getopt和set之后,命令行会变为: -a -b arg -c -- arg1 $1指向-a,$2指向-b,$3指向arg,$4指向-c,$5指向--,而多出的arg1则被放...
The final portion of the batch script contains commands along with their options and arguments. The commands are executed in the order they are listed within the script. They may be regular Unix utilities or parallel programs, but to invoke them in parallel (create multiple processes), thesrunc...
The first and the most straight forward approach to run a shell command is by usingos.system(): importosos.system('ls -l') If you save this as a script and run it, you will see the output in the command line. The problem with this approach is in its inflexibility since you can’...
