Functions: cut echo md5sum sed

Command makes use of the Malware Hash Registry (http://www.team-cymru.org/Services/MHR/).

It parses the current directory and subdirectories and calculates the md5 hash of the files, then prints the name and sends the hash to the MHR for a lookup in their database.

The 3rd value in the result is the detection percentage across a mix of AV packages.

find . -name \*.php -exec php -l "{}" \;
for i in $(find . -name *md5checksum_file* | sed 's/\(\.\/.*\)md5checksum_file.txt/\1/'); do cd "$i"; md5sum -c "md5checksum_file.txt"; cd -; done | tee ~/checksum_results.txt | grep -v "<current directory>"

Functions: cd find grep md5sum sed tee

extracts path to each md5 checksum file, then, for each path, cd to it, check the md5sum, then cd - to toggle back to the starting directory. greps at the end to remove cd chattering on about the current directory.

Functions: time

This one-liner is for cron jobs that need to provide some basic information about a filesystem and the time it takes to complete the operation. You can swap out the di command for df or du if that's your thing. The |& redirections the stderr and stdout to the mail command.

How to configure the variables.




FSCKDEV=`grep $TOFSCK /proc/mounts | cut -f1 -d" "`

MAILSUB="weekly file system check $TOFSCK "

HTMLTEXT=$( curl -s http://www.page.de/test.html > /tmp/new.html ; diff /tmp/new.html /tmp/old.html ); if [ "x$HTMLTEXT" != x ] ; then echo $HTMLTEXT | mail -s "Page has changed." mail@mail.de ; fi ; mv /tmp/new.html /tmp/old.html

Functions: diff echo mail mv

Checks if a web page has changed. Put it into cron to check periodically.

Change http://www.page.de/test.html and mail@mail.de for your needs.

perl -e '$p=qr!(?:0|1\d{0,2}|2(?:[0-4]\d?|5[0-5]?|[6-9])?|[3-9]\d?)!;print((shift=~m/^$p\.$p\.$p\.$p$/)?1:0);'
