system check

[Kenn Chen]

How could I check my server with all the output save into a file and i only need to check the file instead of checking command by command in Unix. Foe instances, I want to use dmesg,ioscan -fn, bdf commands and all output should save into a file called "syscheck.dat" file.

Hi:

You could do something like this:

#!/usr/bin/sh
F=/tmp/syscheck.dat
date > $F
dmesg >> $F
ioscan -fn >> $F
bdf >> $F

Note that the '>>' causes output to be appended whereas '>' results in output overwriting a file (or creating a new one if none exists).

Hi Chen,

As another option, you could create a script with the following:

#!/usr/bin/sh
exec > /tmp/syscheck.dat 2>&1
date
dmesg
ioscan -fn
bdf
....all other commands you may need

The line 'exec > /tmp/syscheck.dat 2>&1' redirects all output and errors to file syscheck.dat, so you don't need to redirect every command in the script.

Best regards,

Dan

Hi Chen and all others,

i think it's a good idea to check/integrate the syslog files too.
I would use the cron to start the script at several times.
Have fun !!
