本文主要是介绍shell script define functions,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
As we all know, shell scripts can define functions
Here are some of the functions I use
1.Defines a function that displays a progress bar
[root@ali-devan ~]# cat progress.sh
#!/bin/bash
function Progress() {
i=''
echo -e "\033[32m$1\033[0m"
for ((j=0;$j<=100;j++))
do
printf "Progress:[%-100s]%d%%\r" $i $j
sleep 0.05
i=#$i
done
}
Progress "System will reboot"
echo
reboot
#(The purpose of this script is to restart the system after five seconds, and the process is visually visible)2.Defines a function that shows whether a script executes correctly or wrongly for each command
[root@ali-devan ~]# cat judge.sh
#!/bin/bash
function judge() {
if [ $? -eq 0 ];then
echo -e "\033[32m$1======>success\033[0m"
else
echo -e "\033[31m$1======>fail\033[0m"
fi
}
ls
judge "Displays the files in the current directory"
#(The purpose of this script is to check whether each command is executed successfully)
