No bash solution yet, so here it goes (pure bash, no external binaries):

STR=" one two three four " ARR=($STR) LEN=${#ARR[*]} LAST=$(($LEN-1)) ARR2=() I=$LAST while [[ $I -ge 0 ]]; do ARR2[ ${#ARR2[*]} ]=${ARR[$I]} ## push I=$(($I-1)) done echo ${ARR2[*]}

[choroba]: Isn't Using PerlPod Creatively rather a meditation?
[choroba]: I don't see a question
[1nickt]: ugh, I stuck my head in the bass bin for 30 seconds on a dare at Ted Nugent at Hammersmith Odeon. Yes, I am 40% deaf now.
[johngg]: My daughter is incredibly jealous of my wife who got to see The Clash at Brixton many years ago. They went to see The Vaccines there recently.
[1nickt]: But the bands are even louder! I saw Spearhead (Michael Franti) at an outdoor show and had to walk a mile away to not feel pain in my chest! Babies were crying ... I asked the sound engineer why it was necessary to have the bass so loud and he laughed...
[Discipulus]: but the best i attended live was Mano Negra Patchanka at Forte Prenestino .. in 1990
[Corion]: Hmmm - Mano Negra or at least Manu Chao seem to put on a good live show. At least the one live CD I have from Manu Chao sounds good ;)
Discipulus feels the same jealousity of the johngg's daughter
[1nickt]: choroba I agree
[choroba]: Playing in a punk rock band for 20 years... my hearing is quite bad
