I'd happily recommend it. I like the K&R book too - it feels reeeeeeally old but it's really short. There's a few others that have helped me in various ways but these are a little older - Love C by Tim Love (free online, my copy is something i just printed out, it's not that long). Programming from the Ground Up (x86 assembly) - this is available freely online but i bought the book and that helped me a lot with C even though it's a book with only assembly... (to be fair, it does go through calling conventions). Finally there's another book i love, Advanced Programming in the Unix Environment by Stevens, i have the 6th edition updated by Rago after Stevens' passing. Fascinating book - but huge.
