I have server A test-lx
, and server B test2-lx
, I want to transfer files from server A to server B. While transfering the files i'll need to create a driectory only if it's not exist, how can i check if a directory exist during the lftp conenction? How can i out several files in one command instead of doing this in 2 lines. Is there an option to use find -maxdepth 1 -name DirName
Here is my code:
lftp -u drop-up,1Q2w3e4R ftp://ta1bbn01:21 << EOF
cd $desFolder
mkdir test
cd test
put $srcFil
put $srcFile
bye
EOF
Simple way with ftp:
#!/bin/bash
ftp -inv ip << EOF
user username password
cd /home/xxx/xxx/what/you/want/
put what_you_want_to_upload
bye
EOF
With lftp:
#!/bin/bash
lftp -u username,password ip << EOF
cd /home/xxx/xxx/what/you/want/
put what_you_want_to_upload
bye
EOF
From lftp manual:
-u <user>[,<pass>] use the user/password for authentication
You can use mkdir for create a directory. And you can use put command several time like this:
put what_you_want_to_upload
put what_you_want_to_upload2
put what_you_want_to_upload3
And you can close connection with bye
You can check folder is exist or not like this:
#!/bin/bash
checkfolder=$(lftp -c "open -u user,pass ip; ls /home/test1/test1231")
if [ "$checkfolder" == "" ];
then
echo "folder does not exist"
else
echo "folder exist"
fi
From lftp manual:
-c <cmd> execute the commands and exit
And you can open another connection for put some files.
I don't know how to check folder is exist or not with one connection, but I can do that like this. Maybe you can find better solution:
#!/bin/bash
checkfolder=$(lftp -c "open -u user,pass ip; ls /home/test1/test2")
if [ "$checkfolder" == "" ];
then
lftp -u user,pass ip << EOF
mkdir test2
cd test2
put testfile.txt
bye
EOF
else
echo "The directory already exists - exiting"
fi
I used the same basic coding outline as phe however I found that using ls /foldername will output "folder does not exist" if the folder is empty. To solve this I use
#!/bin/bash
checkfolder=$(lftp -c "open -u user,pass ip; ls | grep /test1231")
if [ "$checkfolder" == "" ];
then
echo "folder does not exist"
else
echo "folder exists"
fi
Please note this only works if the folder is in the root directory. For sub directories in a folder the following should work.
#!/bin/bash
checkfolder=$(lftp -c "open -u user,pass ip; find | grep home/test1/test1231")
if [ "$checkfolder" == "" ];
then
echo "folder does not exist"
else
echo "folder exists"
fi
First prepare credentials record into ~/.netrc file as:
machine site-url-here
login user-login-here
password user-password-here
so you don't have to expose your password on the command line to use this in script.
Then call:
lftp -e "lftp-command-here" ftps://user-login-here@site-url-here/initial-folder-here/`
In my case I run mget -c *
lftp command for getting all logs from java spring boot application running linux app instance at azure infrastructure. Of course you can put your commands separated by semicolon there.
