frequency of occurence there is no need to sort ; here a solution with bash shopt -s extglob; N=10000; while read n;do [[ $n = *(0-9) ]]&&((a[n/N]++));done; for i in ${!a[*]};do echo $((i*N))-$(((i+1)*N-1)) $((a[i]));done |

Generate “item tag” pairs from “item,item,…|tag” lists full bash version : while IFS="|" read i t;do while read -d, j;do echo "$j$t";done <<<"$i,";done <test.txt, may be more efficient on small files but for larger files awk will be a better choice |

/dev/tcp listen instead of nc listen +1 the bash allows to create the client socket but the server socket you can use nc or can be implemented with perl or c, in fact server process will loop accepting connections and spawning processes or creating threads or it can accept only one connection by one |

Is there a way to get *actual* (uninterpreted) shell arguments in a function or script? It may be a solution using history but will not work in all cases, so i don't recommend |
