I am creating a script to sync my important documents between two system. I want my script to generate a log file for the last action. can you suggest me a way to achieve this.Question: If I execute the rsync command with -v flag, it will print a lot of messages on the console. Is there any way. So, I can redirect these logs to a file?

Let's say I am pinging a host, and want to output to a file each reply and its timestamp of when this started.
I know that it can be done with a loop and a shell script. Something like this
DO
echo "$(date)" >> results.txt ###includes the time and outputs results to txt###
ping -c 4 HOST >> results.txt ###a total of 4 pings at a rate of 1 per second###
REPEAT UNTIL USER PRESSES CTRL-C
Now, my first issue is that I need to be able to see results real-time as well.
Is there a way one can print to BOTH a screen and output? If one uses the ">>" command, it is essentially sending everything to the file. Running another ping command in parallel is not an option.
This seems so simple when doing it from command line but I'm not able to accomplish it inside a script. I am trying to put output of following command into a text file:
CMD= mysql -uroot -psecret -e 'SHOW SLAVE STATUS G;'
FIL=~/replication-`date +%F`.txt
MAILTEXT=~/mailtext.txt
touch $FIL
$CMD > $FIL
Where FIL is a variable that contains path of the file to which to output command. I am running this command in a shell script from where I want to email contents of $FIL as attachment using mutt. But I am always getting 0 byte file. Also if I examine in directory the file is of 0 byte length.
For example I want a file to be processed by sed, and then overwrite the file with sed's output. I would try this:
Code:
sed '<regex goes here>' myfile > myfile
But it doesn't work as expected, instead it empties the file (I am thinking that as the first byte comes out of sed, it overwrites the whole file and sed has nothing more to do). How can I make this work?

I am using an awk command to print a line from a cvs file.the awk command includes an if statement that filter the output-lets say i want to print all the lines that the price field is greater than 30.i have it working when i put the parameters myself.. but when i try to send them with vars it wont work..i am sending the sign of the if statement - can only be: == , < , >it looks like this:
cat file.csv | awk -v sign=">" -v field="2000" '{if($3 sign field) printf "%-12s%-12s%-12s%-12s
",$1,$2,$3,$4}' FS=,
the bold part is the problem , because when i put the sign parameter myself t works great.. i guess its a chars issue but i cant spot it

i treid the below on line 8 :
1- send "show command;

2- logsave logfile.txt 'send "show command;

3- i simply tried to send the output of the whole script to file logsave /home/logfile ./script : seems that logsave work under root only
4- ./script > logfile : the problem with this is that the output of echo or (read "enter your id") command will not be displayed on the screen (actually nothing will be displayed, i have to open the log file to see the output). is there any way to save the log of the "send" ? or to save the log of the complete script without hiding the output on the screen?

I can do that for a file, but for a directory, it is printing the contents of the directory as well. Lets say there is a directory called doc, and there are more than one occurrences of that directory.
find . -name "doc" -type d -exec ls -l {} ;
This is printing the contents of all the files under doc directory as well.
