Disaster Snapshot (procmail)

Required: 1) Systems that send out alert emails when errors, database locks, etc occur. 2) a system that: a) has the ability to receive emails, and has procmail installed. b) has ssh keys set up to machines that would send out alerts. When procmail receives alert email, you can issue a command like this one (greps and awks may very - you're isolating the remote hostname that had the issue). This will pull process trees from the alerting machines, which is always useful in later analysis. Show Sample Output

run complex remote shell cmds over ssh, without escaping quotes

I was tired of the endless quoting, unquoting, re-quoting, and escaping characters that left me with working, but barely comprehensible shell one-liners. It can be really frustrating, especially if the local and remote shells differ and have their own escaping and quoting rules. I decided to try a different approach and ended up with this.

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

Selecting a random file/folder of a folder

Also looks in subfolders

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

generate random password

for Mac OS X

Summarize the number of open TCP connections by state

Useful for checking the number and state of TCP connections.

pattern match in awk - no grep

Rather than chain a string of greps together and pipe them to awk, use awk to do all the work. In the above example, a string would be output to stdout if it matched pattern1 AND pattern2, but NOT pattern3.

Extract all 7zip files in current directory taking filename spaces into account

Change host name

With sed you can replace strings on the fly.

File rotation without rename command

Rotates log files with "gz"-extension in a directory for 7 days and enumerates the number in file name. i.e.: logfile.1.gz > logfile.2.gz I needed this line due to the limitations on AIX Unix systems which do not ship with the rename command.

bash screensaver (scrolling ascii art with customizable message)

Displays a scrolling banner which loops until you hit Ctrl-C to terminate it. Make sure you finish your banner message with a space so it will loop nicely.
