bash script code help to make zip/tar of several folders
提问by Arshdeep
I am very new in bash and never coded in before but this task is stuck so need to get rid of it . I need to make bash script to make a single compressed file with several dirs.
我对 bash 很陌生，以前从未编码过，但这项任务被卡住了，所以需要摆脱它。我需要制作 bash 脚本来制作一个包含多个目录的压缩文件。

/var/system/
and all will be compressed to single file /var/file/bkup.[zip][tar.gz]
所有将被压缩到单个文件 /var/file/bkup.[zip][tar.gz]
Thanks in advance

# tar: (c)reate g(z)ip (v)erbose (f)ile [filename.tar.gz] [contents]...
tar -czvf /var/file/bkup.tar.gz /home/code/bots /var/config /var/system
# zip: (r)ecursive [filename.zip] [contents]...
zip -r /var/file/bkup.zip /home/code/bots /var/config /var/system

The problem as you've described it doesn't require a bash script, just tar.
您所描述的问题不需要 bash 脚本，只需要tar.
tar cvzf /var/file/bkup.tar.gz /home/code/bots/ /var/config/ . . . /var/system/

You could create a bash file for it, if you intend to run it in a cronjob for example and add some other commands like a mysqldump beforehand
您可以为它创建一个 bash 文件，例如，如果您打算在 cronjob 中运行它并预先添加一些其他命令，例如 mysqldump
You need to create a file like backup.sh with the following contents
(You may need to alter the path to bash, you can find bash with whereis bash)
你需要创建一个像backup.sh这样的文件，内容如下（你可能需要改变bash的路径，你可以用 找到bash whereis bash）
#!/bin/bash
#
# Backup script
#
# Format: YEAR MONTH DAY - HOUR MINUTE SECOND
DATE=$(date +%Y%m%d-%H%M%S)
# MySQL backup file
MYSQLTARGET="/var/file/backup-mysql-$DATE.sql"
# Target file
TARTARGET="/var/file/backup-$DATE.tar.gz"
# MySQL dump
# you cannot have a space between the option and the password. If you omit the password value
# following the --password or -p option on the command line, you are prompted for one.
mysqldump -u root -ppassword --all-databases > $MYSQLTARGET
tar -czvf $TARTARGET $MYSQLTARGET /home/code/bots /var/config /var/system
PS. This is untested code. It's just an example of how a bash script works in the current replied context.
附注。这是未经测试的代码。这只是 bash 脚本如何在当前回复的上下文中工作的一个示例。
