i need write shell script re-format file inserting line breaks. condition line break should inserted when encounter comma in file. for example, if file delimiter.txt contains: this, file, should, added, a, line break, when find, comma. the output should be: this file should added line break when find a comma. can done grep or awk ? using gnu sed : sed 's/, /\n/g' your.file output: this file should added line break when find a comma. note: syntax above work on system have \n line delimiter linux , unixes. if need portal solution in a script use following expression uses literal new line instead of \n : sed 's/,[[:space:]]/\ /g' your.file thanks @edmorten advice.

the following python code produces [(0, 0), (0, 7)...(0, 693)] instead of expected list of tuples combining of multiples of 3 , multiples of 7: multiples_of_3 = (i*3 in range(100)) multiples_of_7 = (i*7 in range(100)) list((i,j) in multiples_of_3 j in multiples_of_7) this code fixes problem: list((i,j) in (i*3 in range(100)) j in (i*7 in range(100))) questions: the generator object seems play role of iterator instead of providing iterator object each time generated list enumerated. later strategy seems adopted .net linq query objects. there elegant way around this? how come second piece of code works? shall understand generator's iterator not reset after looping through multiples of 7? don't think behavior counter intuitive if not inconsistent? as discovered, object created generator expression iterator (more precisely generator-iterator ), designed consumed once. if need resettable generator, create real generator , use in loops: def multiples_of_...
