The for loop for loop script syntax and examples

In the shell for loop commonly used to perform a limited number of cycles, and while it is generally an infinite loop, and so on for daemons

grammar:

i: variable name

words: variable ranges

command: Command

for i in words; do
    #command
done

Off now, we use a for loop to write a simple script to display the file in the current directory:

words=`ls /root/`
for i in words; do
    echo $i
done

[root@node1]# sh test.sh 
anaconda-ks.cfg
bootime.svg
git_test
monitor
null
