A young man from Hawaii who found the ukelele a much more versatile instrument than his forebears is featured in the well-made documentary “Jake Shimabukuro: Life on Four Strings” (PBS, 9 p.m., check local listings). Shimabukuro, who pronounces the instrument “ook-ulele” and gained fame on line with a striking instrumental version of “While My Guitar Gently Weeps” (by another noted ukelele aficionado, George Harrison) gets a chance to play quite a bit in the hour-long film.
“Touch” (Fox, 9 p.m.) reaches its bitter end tonight. Just yesterday, the network announced it wasn’t picking it up for a third season. Don’t despair in never seeing Keifer Sutherland on TV again, though. There is, however, surprising talk of a short revival of “24.”
There’s almost no chance “Vegas” (CBS, 9 p.m.) will be renewed, though nothing is official. Too bad, they put a lot of money in creating an early 60s Sin City set and had a cast that included Michael Chiklis and Dennis Quaid.

“Nikita” (The CW, 8 p.m.), which is not having a season finale tonight, is officially coming back next season, the network announced yesterday. But it will then present its six final episodes.

The former star of “Full House” and “America’s Funniest Videos” reaches deep into the gutter for his latest comedy special, “Bob Saget: That’s What I’m Talkin’ About” (Showtime, 10 p.m.). But some people like that side of him.
Mark Bittman, Charles Cooke, Glenn Greenwald, Joy Reid and Zachary Quinto are on a new “Real Time with Bill Maher” (HBO, 10 p.m.).
Later, on “Vice” (HBO, 11 p.m.) they take a look at ghost cities being built in China and the aftermath of Arab Spring in Egypt.
Workers that stood out in the four seasons of “Undercover Boss” (CBS, 8 p.m.) are featured on tonight’s clip show.
A movie about motorcycle racing is pitched on “Shark Tank” (ABC, 9 p.m.).
More about Jodi Arias on “Dateline” (NBC, 9 p.m.). “Rock Center with Brian Williams “(NBC, 10 p.m.) talks with New Jersey Gov. Chris Christie about his weight-loss surgery.
A solid new episode of “Maron” (IFC, 10 p.m.) concerns finding a possum in his crawl space, or hiring an assistant to fish it out for you. Denis Leary also shows up for Marc Maron’s podcast.
