Sorry to keep bugging you guys about this stuff. I now have a backup script that works for everything except one small part. This backup script can rsync and create a tarball to push out to a mount point with zero issues, but when i try to push the tarball via ftp, it craps out on me. I can run the command manually with no issues so it is not the command. I must be missing something in the order of the script that I just can not see. an extra group of eye might just see it right off the bat.

Code:

#!/bin/bash

### This script is to be called with the following options:

# t for tar compressed and verified file to be pushed to any device.

# f for ftp will also use the tar function to generate the file.

# r for rsync, this will not use the tar compression.

# n for no kill mode.  this will not terminate any interfaces or rx30 screens.

# x this will be used for debug mode to troubleshoot the script to see 

#  were it might be breaking.

# You may call this script with a combination of options.  Example:  back f n x will call the FTP

# backup, typically to a NAS device, it will NOT close any screens or interfaces, and will fully

# display the rest of the script as it makes calls to functions, creates the tarball, 

# and connects to the NAS device for lftp transmission.

above is the output with the -xv option. you can clearly see that for what ever reason the lftp is not working properly.

Code:

[rx30@rx30 ~]$ lftp -e 'set ftp:passive-mode on && cd rayb && put /tmp/rx-2012-

Apr-10-Tue-08.27.tar.bz2.enc && bye' -u junk,junk ftp.rx30123.com

cd ok, cwd=/rayb

845390 bytes transferred

so what did i mess up in the script that is causing the lfpt to run in a loop instead of doing its job of putting the file up on the ftp server?

the lftp command and the lftp function have the same name.

You named the function as the lftp command, so that every time you call lftp inside the function it calls itself recursively in an endless loop. Rename the function and the trick is done.

You should change your thread's title,giving more information in it.So others can help you.

thanks, i also found an other error. i was using the variable username in two different locations with two different =<stuff> changed the 2nd one from username => USER, i will also replace the name of the lftp function. ty

those 2 fixes did the trick. many thanks a.. making as solved.

Another way to avoid recursion is to use the command built-in.

Code:

foo() {

        command foo <options>

}

In addition:

1)
QUOTE ALL OF YOUR VARIABLE SUBSTITUTIONS. You should never leave the quotes off a parameter expansion unless you explicitly want the resulting string to be word-split by the shell (globbing patterns are also expanded). This is a vitally important concept in scripting, so train yourself to do it correctly now. You can learn about the exceptions later.

http://mywiki.wooledge.org/Arguments
http://mywiki.wooledge.org/WordSplitting
http://mywiki.wooledge.org/Quotes

2)
It's recommended to use ((..)) for numerical tests, and [[..]] for string tests and other complex expressions. Don't use the old [..] test unless you specifically need POSIX-style portability.

http://mywiki.wooledge.org/ArithmeticExpression
http://mywiki.wooledge.org/BashFAQ/031
http://wiki.bash-hackers.org/commands/classictest
http://wiki.bash-hackers.org/syntax/...nal_expression

3)
Clean, consistent formatting makes code readable and more easily debuggable. Indent all your sub-commands, and separate logical sections with whitespace. Add comments anywhere the code isn't completely obvious (and remember, what seems obvious to you now will not be a year or so down the line).

Many people also think that it's more readable to place the "do/then" keywords on the same line as the "for/while/until/if" keywords, as it more clearly separates the outside block from the inside block.

Code:

for var in fee fai foo fum ; do



        if [[ "$var" == "foo" ]]; then

                echo "Found 'foo'."

        fi



done

Environment variables are generally all upper-case. So while not absolutely necessary, it's good practice to keep your own user variables in lower-case or mixed-case, to help differentiate them.

Finally, this is just my opinion, but using the full ${variable} pattern everywhere does nothing but make the code look more cluttered and harder to read. I suggest leaving the brackets off when you don't need them.

4)
You have a large number of lines like this:

Code:

MAXBACKSIZE=`df -hk | grep ${MOUNTDIR} | awk -F" " '{print $2}'`

To start with, $(..) is highly recommended over `..`.

Second, Useless Use Of Grep. Awk can do all of the pattern matching itself. Just import the bash variable value into an awk variable.

Third, since the same command is repeated so often, set up a function for it.

Code:

getsize() {

        # $1 is the pattern to match, $2 is the column number to print



        df -hk | awk -v "pattern=$1" -v "colnum=$2" '( $0 ~ pattern ) { print $colunum }'



}



maxbacksize=$( getsize "$mountdir" 2 )

Thank you David the H. I will read over that, but here are some adjustments I have made to the script. It is now functioning as expected.

Code:

# f for ftp will also use the tar function to generate the file.

# r for rsync, this will not use the tar compression.

# n for no kill mode.  this will not terminate any interfaces or rx30 screens.

### Notes for e-mail

### yum -y install postfix

### cd /var/spool/postfix

### mkfifo pickup

### postsuper -d ALL        ## This is to clear the printer queue a MUST on FC5/7 systems.

### service postfix restart

### chkconfig postfix on        ###this will set postfix to start on bootup###

### uncomment the following line to send e-mail everytime the script runs

# mailx -s "backup logs ${license}" user@123.net user2@123.net < ${LOG}

# echo "mailx -s "backup logs ${license}"  user@123.net user2@123.net < ${LOG}" >> ${LOG}



exit;

I will also look into what you linked to see about improving the script further.
