Question

我尝试使用脚本gzip文件，但它不起作用并继续抛出错误。有人可以就这个脚本的问题给出一些指导吗？

DEFAULTDIRECTORY=”/Backup”
if [ -d "$DEFAULTDIRECTORY" ]; then 
mkdir -p /backup 
fi # Makes directory if the directory does not exist

# Set the timestamp for the backup
TIMESTAMP=`date +%Y%m%d.%H%M`

# let the user choose what they want to backup
echo -n "Select the file or directory you want to backup" 
read Chosendata 



# read the backup file name file
echo -n "Select the file name" 
read FNAME

# start the backup.
echo -e "Starting backup"

# compress the directory and files, direct the tar.gz file to your destination directory
tar -vczf ${FNAME}-${TIMESTAMP}.tar.gz ${Chosendata} > ${DEFAULTDIRECTORY}

# end the backup.
echo -e "Backup complete"

Answer 1

将tar命令的输出重定向到DEFAULTDIRECTORY不会执行注释指定的内容。

我认为您要做的是将文件保存在DEFAULTDIRECTORY。

中

更改行

tar -vczf ${FNAME}-${TIMESTAMP}.tar.gz ${Chosendata} > ${DEFAULTDIRECTORY}

到

tar -vczf $DEFAULTDIRECTORY/${FNAME}-${TIMESTAMP}.tar.gz ${Chosendata}

Answer 2

您需要否定此测试if [ -d "$DEFAULTDIRECTORY" ]; then - ＆gt; if [ ! -d "$DEFAULTDIRECTORY" ]; then。您不应该使用tar命令重定向。相反，你应该在tar.gz文件前加上它：

tar -vczf $DEFAULTDIRECTORY/${FNAME}-${TIMESTAMP}.tar.gz ${Chosendata}

Answer 3

试试这个：

#!/bin/bash

DEFAULTDIRECTORY="/Backup"

# Makes directory if the directory does not exist
# Here you had an inverted statement: use "if [ ! -d ... ] then" or "[ -d ... ] ||" 
[ -d "${DEFAULTDIRECTORY}" ] || mkdir -p "${DEFAULTDIRECTORY}"

# Set the timestamp for the backup
# For subshell command you can use `...` or $(...)
TIMESTAMP=$(date +%Y%m%d.%H%M)

# Let the user choose what they want to backup
# You can use the -p (prompt) option instead of using echo
read -p "Select the file or directory you want to backup: " CHOSENDATA 

# Read the backup file name
read -p "Select the file name: " FILENAME

# Start the backup.
echo "Starting backup"

# Compress the directory, direct the tar.gz file to your destination directory
# tar 'create' ' zip' 'verbose' 'force' <The output filename> <The data you want to backup>
tar -czvf ${DEFAULTDIRECTORY}/${FILENAME}-${TIMESTAMP}.tar.gz ${CHOSENDATA}

# End the backup.
echo "Backup complete"

Bash备份不起作用
