Some of the tools i'm using in day-to-day development - Residing in ~/bin, along with some installations, as follows:

General Tools

• colcount - Converts standard input lines to their respective column counts
• q - See https://github.com/harelba/q
• secs2date - Converts timestamps to human date-time strings
• sigma - Sums up all the numbers from stdin
• xvsy - Draws an XY graph of x values vs y values - Getting pairs of x,y lines from standard input
• categoryvsy - Draws a bar graph for category names vs y values - Getting pairs of category-name,y lines from standard input
• display - Uses disper in order to control multiple monitor setups for the same machine (docked, undocked,home etc.)
• disable-company-settings/enable-company-settings - Allow quick switching between a company provided maven settings.xml and a default one
• svn-diff-meld - Wrapper so svn would work with meld

• hive-table-fields-to-pig-load-command - Converts the output of a hive DESCRIBE command into a Pig LOAD command

Zookeeper related utilities:

• zkfind - get a zookeeper path and lists all nodes recursively, similar to linux find
• zkget - gets the data of a specific node in zookeeper
• zkrmr - Performs a recusrive delete of zookeeper nodes (this capability is included in zkCli if you're using zookeeper >3.4)
• zkgrep - Finds a substring in the data of zookeeper nodes
