Linux bash scripting

有时候你会想在Terminal里执行一些控制命令比如让一个命令执行10次。

Run Command 5 Times

for i in {1..5}; do COMMAND-HERE; done

For Example:

for i in {1..10}; do rosbag play 1080.bag; done

还有一类，对文件操作：

for i in *; do echo $i; donefor i in *.txt; do cp $i /backup; donefor i in $(ls *.gz);do 7z x $i;done
