howto run a script and to copy the output into a file?

[adhg]

Hi all,
I'm writing a bash script that creates a backup of my db and send it to a remote site (this will be done on a daily basis and the remote site will have a folder name of the day of backup, eg., 2007-09-09)

When I run the script, I placed some 'echo' to tell what/where the script is doing.

Since this will be done on automatically and on a daily basis, I would like to create a text file that includes all the *echos* and place it under the folder I created for that specific date (just like a log file that tells what happens and if something went wrong)

on the terminal I can do this:

adhg@ubuntu$ ./backup>out.txt

and all echos will go into out.txt. Problem is, of course, that I can't do this in the script:

cp out.txt $remoteFolder

this is because the out.txt is not completed yet :confused:

any idea how to circumvent this problem?
thanks
adhg

Hi,

You can directly route the output to the remote destination.
adhg@ubuntu$ ./backup>$remotefolder/out.txt

And since you want to aggregate the logs datewise;
You might as well do
adhg@ubuntu$ ./backup>$remotefolder/`date +%Y-%m-%d-%T`/out.txt

HTH.

The easiest solutions is to write a wrapper script that does exactly what you want:

For instance:


#!/bin/bash

bash ./backup > ./out.txt

cp ./out.txt $remoteFolder

or change all the echos in your script to echo to the file and then cp at the end of the script/loop

log=`date +%Y-%m-%d-%T`.txt

echo "put this in the log" >> $log
