shell The script traverses all the files in the specified folder

#!/bin/bash function readDir(){ #echo $1 #echo $2 targetDir=`ls $1` #
It's on the keyboard '~' The symbol below , It's not a single quotation mark for fileName in $targetDir do if [ -d $1"/"$fileName ] #
There should be spaces at both ends , Otherwise, the report is wrong then #echo $1"/"$fileName readDir $1"/"$fileName $2 else #echo
$fileName #echo ${fileName:0-3} if [[ ${fileName:0-3} == '.py' ]]; # Find extension for
.py File for then echo $1"/"$fileName >> $2/findPy elif [[ ${fileName:0-5} == '.html'

' Traverse target folder path ' and ' Traversal result save path '
Add execution permissions to scripts ：
chmod 755 findClass.sh （7：x： implement =1 + r： read =4 +w： write =2;5：x + r） perhaps chmod +x
findClass.sh
Execute script ：
./findClass.sh ' Traverse target folder path ' ' Traversal result save path '
