Check if a file exist in FTP with an automated bash script
提问by BaFouad
I want to automate a batch job that does the following:
我想自动化执行以下操作的批处理作业：
- check if my file.txtexists in a FTP server, I rename it to file.trt
- check if my file.txtand file.trtexist, if so I send an email
- I run another script
- at the end I delete file.trt
- 检查我的file.txt 是否存在于 FTP 服务器中，我将其重命名为 file.trt
- 检查我的file.txt和file.trt 是否存在，如果存在，我发送电子邮件
- 我运行另一个脚本
- 最后我删除了file.trt
here's what I have done :
这是我所做的：
#!/bin/bash
host='ftp.xxxx.com'
USER='xxxx'
PASSWD='xxxx'
ftp -n -v $host << EOF
ascii
user $USER $PASSWD
prompt
mls /TEST/file.txt test.txt
quit
EOF
if [[ $? -eq 0 ]]
then
echo "The File file.txt Exists";
else
echo "The File file.txt dons not Exist";
fi
Am confused and don't know how to do it, can someone please help me?

then
echo "" | mail -s "aaaaa] Error, aaaaa." [email protected] -c [email protected]
elif grep -inr '/TEST/file.txt' test.txt
