bash - 来自 cron 的脚本不运行

Question

我有一个脚本：

-rwx------. 1 root root 135 Oct 15 12:00 /backup/purge.sh

#!/bin/bash
volume=`echo "list volumes" | bconsole|grep -i "Append\|Full"|awk '{print $4}'`
echo "purge volume=$volume yes" | bconsole

如果我手动运行它，它会运行。

如果我把脚本放到 crontab 它不会运行，但是日志说它运行了。

Oct 15 16:07:01 sdfdsfdsf CROND[36326]: (root) CMD (/backup/purge.sh)

日程安排：

07 16 * * * /backup/purge.sh

如果我手动运行：

/backup/purge.sh

purge volume=Vol-0001 yes

This command can be DANGEROUS!!!

It purges (deletes) all Files from a Job,
JobId, Client or Volume; or it purges (deletes)
all Jobs from a Client or Volume without regard
to retention periods. Normally you should use the
PRUNE command, which respects retention periods.
Automatically selected Catalog: MyCatalog
Using Catalog "MyCatalog"
1 File on Volume "Vol-0001" purged from catalog.
There are no more Jobs associated with Volume "Vol-0001". Marking it purged.

Answer 1

bconsole 不在 PATH 中，所以我使用了 bconsole 命令的完整路径，如下所示：

!/bin/bash

音量= echo "list volumes" | /sbin/bconsole|grep -i "Append\|Full"|awk '{print $4}' echo "清除音量=$volume 是" | /sbin/bconsole
