我正在尝试制作一个在远程服务器的日常cron作业上运行的bash脚本，以通过ssh自动登录到另一个unix框，运行一些命令，然后退出.

I am trying to make a bash script that runs on my remote server's daily cron jobs to automatically login through ssh to another unix box, run a few commands and then leave.

#!/bin/bash
ssh machinehost.com -l admin -p 2222 "/usr/bin/find /share/Public/backups/set0 -mtime +14 | xargs rm -f;
                               /usr/bin/find /share/Public/backups/set1 -mtime +4 | xargs rm -f;
                               /usr/bin/find /share/Public/backups/set2 -mtime +3 | xargs rm -f;
                               /usr/bin/find /share/Public/backups/set3 -mtime +21 | xargs rm -f;
                               /usr/bin/find /share/Public/backups/set4 -mtime +2 | xargs rm -f;
                               /usr/bin/find /share/Public/backups/set5 -mtime +2 | xargs rm -f;
                               "

我遇到的问题是，我需要修改当前的现有代码，以在执行诸如

The problem I am having is I need to modify my current existing code to do something a little more complicated before each command like

if [ $(ls /share/Public/backups/set1 -1 | wc -l ) -gt 4 ] then run above command
fi

我该如何在远程ssh机器上而不是在本地cron机器上运行此命令?

How would I go about running this command on the remote ssh machine and not on my local cron one?

推荐答案

尝试在本地编写bash脚本并调用:

Try writing your bash script locally and calling:

ssh [e-mail] 'bash -s' < local_script.sh
