删除并压缩目录中的文件

Question

#! /usr/bin/bash
DIRECTORY=/main/dir/sub-dir
if [ -d $DIRECTORY ]; then
find $DIRECTORY/ '*' -maxdepth 1 -mtime +1 -exec rm -rf {} ;;
#Zip Files generated within the last six hour
find $DIRECTORY/ '*' -maxdepth 1 -mmin -360 -exec gzip {} ;
fi
I'm using this command to remove files generated within the last , however the output has the following errors

Error messages :
-bash-4.2$ ./zip_files.sh
find: â*â: No such file or directory
gzip: /main/dir/sub-dir is a directory -- ignored

Files in this directory will be of these sequence, 
-rw------- 1 postgres dba 16777216 Sep 23 23:37 000000010000224300000015
-rw------- 1 postgres dba 16777216 Sep 23 23:37 000000010000224300000016
-rw------- 1 postgres dba 16777216 Sep 23 23:37 000000010000224300000017
-rw------- 1 postgres dba 16777216 Sep 23 23:37 000000010000224300000018
-rw------- 1 postgres dba 16777216 Sep 23 23:37 000000010000224300000019
-rw------- 1 postgres dba 16777216 Sep 23 23:37 00000001000022430000001A

我只想删除已删除和gzipped的文件，并压缩错误消息

感谢您的回复。

您的脚本可能如下所示。注意引号，注意不带空格的未引号*的用法、注意find参数，请参阅man find。用shell检查你的脚本！

#!/usr/bin/env bash
# prefer upper case variables only for exported variables
directory=/main/dir/sub-dir
if [[ -d "$directory" ]]; then
find "$directory"/* -maxdepth 1 -type f 
'(' -mtime +1 -delete ')' -o 
'(' -mmin -360 -exec gzip {} ';' ')'
fi

使用bash数组，您可以在长参数行之间放置注释：

cmd=(
find "$directory"/* -maxdepth 1 -type f
# delete somthing
'(' -mtime +1 -delete ')' -o
# gzip them
'(' -mmin -360 -exec gzip {} ';' ')'
)
"${cmd[@]}"
