Get the names of all folders under the specified directory /usr/ and output:
Shell code:
#!/bin/bash
#Method 1dir=$(ls -l /usr/ |awk '/^d/ {print $NF}')
for i in $dir
do
echo $i
done
#######
#Method 2for dir in $(ls /usr/)
do
[ -d $dir ] && echo $dir
done
##Method Three
ls -l /usr/ |awk '/^d/ {print $NF}' ## In fact, the same method can be displayed directly without the for loop
After running the shell, the names of all folders in the /usr/ directory will be output:
[root@localhost ~]# ./ bin etc games include lib lib64 libexec local sbin share src
The above example of the shell obtaining the names of all folders in the directory and outputting them is all the content I share with you. I hope you can give you a reference and I hope you can support me more.
