Full Discussion: Unable to pass a space inside a variable shell scripting
Operating Systems HP-UX Unable to pass a space inside a variable shell scripting Post 302843635 by Don Cragun on Wednesday 14th of August 2013 08:51:36 AM

First, this all seems to be a very convoluted way of getting output from the command:
Code:
date '+%b %e'

Second, if you save the output from the above command in a variable:
Code:
p=$(date '+%b %e')

and then print that value using echo without quotes, you are throwing away the fact there the date command will put two spaces between the abbreviated month name and the day of the month for the 1st nine days of every month. If you want to preserve the spacing, use:
Code:
echo "$p"

not:
Code:
echo $p

There is a big difference between being able to pass a space in a variable and getting the shell to recognize that two spaces are different that one space when you subject the contents of that variable to word splitting.

To get what you want out of the log file, there are lots of ways to do it depending on your shell. With any standards conforming shell (such as bash or ksh), try:
Code:
tail -n 1 /var/adm/syslog/syslog.log|(
    read abmon dom
    printf "%s %2s" $abmon $dom
)

or:
Code:
tail -n 1 /var/adm/syslog/syslog.log|awk '{print substr($0, 1, 6)}'
