【问题描述】:
我正在尝试编写一个执行以下操作的简单备份脚本:
#!/bin/bash
#backupScript
mysqldump mysql -uxxxxx -pxxxxx Database1 Database2 | gzip > "MainWordPress.gz"
time_stamp = `date +%Y%m%d.%H%M`
file_name = 'backup-{$time_stamp}.tar.gz'
sources = 'DIR/ MainWordPress.gz'
tar -cvf file_name sources
rm MainWordPress.gz
cp file_name some/destination
但问题是它不喜欢:
./runBackup.sh: line 6: time_stamp: command not found
./runBackup.sh: line 7: file_name: command not found
./runBackup.sh: line 8: sources: command not found
tar: sources: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors
我很困惑……
【问题讨论】:
-
应该是
tar -cvf file_name sources还是tar -cvf "$file_name" $sources? (cp也类似。)$time_stamp不会在'backup-{$time_stamp}.tar.gz'(单引号)中扩展。是时候学习 Bash/shell 脚本教程了吗?
