i've started playing java 8 lambdas , i'm trying implement of things i'm used in functional languages. for example, functional languages have kind of find function operates on sequences, or lists returns first element, predicate true . way can see achieve in java 8 is: lst.stream() .filter(x -> x > 5) .findfirst() however seems inefficient me, filter scan whole list, @ least understanding (which wrong). there better way? no, filter not scan whole stream. it's intermediate operation, returns lazy stream (actually intermediate operations return lazy stream). convince you, can following test: list<integer> list = arrays.aslist(1, 10, 3, 7, 5); int = list.stream() .peek(num -> system.out.println("will filter " + num)) .filter(x -> x > 5) .findfirst() .get(); system.out.println(a); which outputs: will filter 1 filter 10 10 you see 2 first elements of stream proc...

i have following file titi tata toto tata if execute sed -i "/tat/d" file.txt it remove lines containing tat . command returns: titi toto but want remove first line occurs in file containing tat : titi toto tata how can that? you make use of two-address form: sed '0,/tat/{/tat/d;}' inputfile this delete first occurrence of pattern. quoting info sed : line number of `0' can used in address specification `0,/regexp/' `sed' try match regexp in first input line too. in other words, `0,/regexp/' similar `1,/regexp/', except if addr2 matches first line of input `0,/regexp/' form consider end range, whereas `1,/regexp/' form match beginning of range , hence make range span _second_ occurrence of regular expression.
