Linur started her writing career as a satirical columnist in local newspapers. Her first full-length novel was The Siren's Song, a best-selling romantic comedy set on the background of the Scud missile attacks on Tel-Aviv during the Gulf War in 1991. In 1994, the book was adapted into a feature-length film directed by Eytan Fox. The title refers to the air-raid sirens which sounded almost every night during the six weeks of the war. It is the story of an assertive professional woman who experiences emotional growth and romance. At the same time, the book is critical of Tel Aviv's superficial lifestyle. 
Linur's second novel, Two Snow Whites, is about a photographer who finds herself involved in a murder case. Sandler Ella, her third novel, depicts the glamorous life of media broadcasters. Her fourth novel, The Brown Girls, was adapted as a popular television mini-series. Linur has also published a book of humorous essays, The Secret Blonde.
Linur was a co-host on the radio show "The Final Word" on Galei Zahal, Israel's Military Radio. The show paired a liberal and a conservative discussing current events, with Linur playing the liberal part. However, in recent years she has expressed views hostile to liberal groups and persons in Israel. In 2002 Linur called for a boycott of Haaretz newspaper until it fires left-wing journalists Amira Hass and Gideon Levy.
According to the self-described anti-zionist blog Mondoweis, in an interview on Israeli Army Radio in April 2012, Linur was asked to comment on footage taken two days earlier of the attack on a Danish anti-Israel activist by IDF officer Lt. Col. Shalom Eisner. In her response she is quoted as saying "the role reversal – I really-really liked it" because "there’s a certain something in the image, of the Jew wearing his yarmulke [religious hat], who looks, you know, like one of the householders in [Jewish] town, and standing against him is the golden-haired Dane, with the Hitler-Jugend look to him" She went on to suggest that foreign activists "want to solve problems that they have no clue about, and that in any case, they tend to be on the wrong side of it – because they were born anti-Semites and will die anti-Semites – one of the reasons that they come here, of all places, is that it’s a kind of summer camp, they know that they’ll maybe demonstrate, they may bump shoulders with policemen, maybe they’ll get some teargas thrown at them, they’ll catch a bit of actual battle time – a kind of adventure summer camp, at the end of which they’ll go back to their privileged northern nation and homeland and feel how good they’ve been. They don’t go do that in Syria, nor in Iran nor in Jordan, nor in Egypt, because they know that there – they’d be shot at.
