Script df

[Lilly_S]

Basically I want to write a script which will run this [cmd=]df -k[/cmd]

I want it to do it automatically at a certain time and email the output. Can anyone help please?

Don't even need a script.

*/10 * * * *    /bin/df -k | /usr/bin/mail -s "df output" some.email.address 2>&1

parsing a table

Ok. I have changed my structure. I now have my output, however I want to parse it using perl or sed etc. I want to check each % and if it reaches a certain threshold to alert me.

Any idea how?

any idea how?

Yes, using perl or sed. Perl is probably easier if you also want to do something based on the info.

Ok, I will have a look at perl as I am new at this. If anyone has any idea how to do it please let me know.

0. Start perl
1. Execute df and save the output
2. Parse the output
3. Act on the parsed data.

Easy as 1-2-3

Here's a start

df | perl -ne 'next if /^(Filesystem|devfs|procfs|linproc)/;if (/(\d+\%)\s+\S+/){$p=$1;} if( $p > 90){print;}'
