[英]Writing a Bash script to remove all zero length ordinary files in the directory and all sub-directories without using -find
This is what I have but I am pretty sure this only removes the files in the directory and its direct subdirectories.这就是我所拥有的,但我很确定这只会删除目录及其直接子目录中的文件。 How would I target all subdirectories?
我将如何定位所有子目录?
#!/bin/bash
currDir="$PWD" #the current working directory is set as the default
if [ $# -eq 1 ] #if the number of command line args is 1
then
currDir=$1 #use the specified directory
fi
for file in $currDir/*; #iterate through all the files in the directory
do
if [ -s $file ] #if file exists and is not empty
then
continue #do not remove
else
rm -rf $file #if it exists and is empty, remove the file
fi
for file2 in $currDir/**/*; #remove empty files from subdirectory
do
if [ -s $file2 ]
then
continue
else
rm -rf $file2
fi
done
done
You can issue:您可以发出:
find /path/to/your/directory -size 0 -print -delete
This will delete all the files in a directory (and below) that are size zero.这将删除目录(及以下)中大小为零的所有文件。
Would you pleaae try the following:请您尝试以下操作:
#!/bin/bash
traverse() {
local file
for file in "$1"/*; do
if [[ -d $file ]]; then
traverse "$file"
elif [[ -f $file && ! -s $file ]]; then
echo "size zero: $file"
# if the result is desirable, replace the line above with:
# rm -f -- "$file"
fi
done
}
traverse . # or set to your target directory
