I wrote a litte `arrayPopulate` function regarding your request: https://f-hauri.ch/vrac/arrayManip.sh.txt Usage: arrayPopulate [-O origin] [-n number] [-f field by row] $ arrayPopulate -f 3 T {a..c}{0..2} $ dumpArray T [0]='a0 a1 a2' [1]='b0 b1 b2' [2]='c0 c1 c2' $ arrayPopulate -f 3 -O 1 T {d..f}{0..2} $ dumpArray T [0]='a0 a1 a2' [1]='d0 d1 d2' [2]='e0 e1 e2' [3]='f0 f1 f2' $ arrayPopulate -f3 -O2 -n1 T {g..i}{0..2} $ dumpArray T [0]='a0 a1 a2' [1]='d0 d1 d2' [2]='g0 g1 g2' [3]='f0 f1 f2' $ arrayPopulate -f3 -O$((${#T[@]}-1)) T {a..b}{0..2} $ dumpArray T [0]='a0 a1 a2' [1]='d0 d1 d2' [2]='g0 g1 g2' [3]='a0 a1 a2' [4]='b0 b1 b2' This could handle special characters like spaces, tabs and newlines. I've done some tests, this seem to work fine with resonably small amount of datas. $ time arrayPopulate -f 100 myvar {10000..50000} real 0m26.579s user 0m26.242s sys 0m0.116s $ echo Array myvar contain ${#myvar[@]} elements of ${#myvar[0]} characters. Array myvar contain 401 elements of 599 characters. Populating a line of 40001 fields (240Kb) into an array of 401 entries containing upto 599 characters took 26.6 secondes on my host: Core i5-4570 @3.20GHz, with 32Go ram. -- Félix Hauri - <fe...@f-hauri.ch> - http://www.f-hauri.ch
