Simple Video Surveillance by email

This takes a picture (with the web cam) every 5 minutes, and send the picture to your e-mail. Some systems support mail -a "References: " so that all video surveillance emails are grouped in a single email thread. To keep your inbox clean, it is still possible to filter and move to trash video surveillance emails (and restore these emails only if you really get robbed!) For instance with Gmail, emails sent to me+trash@gmail.com can be filtered with "Matches: DeliveredTo:me+trash@gmail.com"

Get AWS temporary credentials ready to export based on a MFA virtual appliance

You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token. This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use: `awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'` You must adapt the command line to include: * $MFA_IDis ARN of the virtual MFA or serial number of the physical one * TTL for the credentials

Open a manpage in the default (graphical) web browser

An easy alias for opening a manpage, nicely HTML formatted, in your set internet browser. If you get a "command exited with status 3" error you need to install groff.

Find files modified since a specific date

This command uses -newerXY to show you the files that are modified since a specific date. I recommend looking for "-newerXY" on the manpage to get the specifics.

Testing php configuration

Run the function phpinfo() on the shell

Find files in multiple TAR files

A quick find command to identify all TAR files in a given path, extract a list of files contained within the tar, then search for a given string in the filelist. Returns to the user as a list of TAR files found (enclosed in []) followed by any matching files that exist in that archive. TAR can easily be swapped for JAR if required.
