Hi,

How to run unix command and store the output in a variable?

set file1 `/tmp/data +%m%d%y`

above syntax not working. Any help would be appreciated.

Thanks.

Hi,

I assume you are trying to store the date in a variable. Try this :-

# set file1=`date +%m%d%y`
# echo $file1

Regards,

Dave.

result=$(command)

However, in your case I think you want

file1="/tmp/data"$(date +%m%d%y)

Mark,

Is he using csh?

So would it be something like :-

set file1="/tmp/data"`date +%m%d%y`

Regards,

Dave.

Guys,

My question was unix command inside expect script not in shell script.Your suggestion didn't work.

Thanks.

What do you want to do with the variable?

Use it after the expect script ends - or during?

It might be easier to run your unix command and output redirect to a logfile?

Usually in expect - it is command, then response....

IE:

# remove all of the files after mgetting them
send_user "Removing Remote Files:\n"
expect "sftp>"
send -- "rm *\r"
expect "sftp>"

send -- "\r\n"
expect "sftp>"
send -- "quit\r"

# close the log file
log_file
expect eof
