linux - Hints for custom bash completion -


i developing custom bash completion command capture job ids scheduling system (lsf, pbs, slurm). i've got basic functionality, extend "hints" i've seen when running zsh.

for instance when press tab in grep example below, get:

grep -<tab>      --after-context          -a           -- specify lines of trailing context      --basic-regexp           -g           -- use basic regular expression      --before-context         -b           -- specify lines of leading context ...

this third column after -- add own bash completion. correct technical term it? hints? compgen provide functionality it?

i attaching current working example provides ids only. example uses lsf.

# lsf job id completion function _mycurrentjobs() {     local cur=${comp_words[comp_cword]}     compreply=( $(compgen -w "$(bjobs -noheader -u $user -o jobid)" -- $cur))     return 0 } complete -f _mycurrentjobs bkill bjobs bstatus bpeek bstop bresume

the command provide ids , desired hints is: bjobs -noheader -u $user -o "jobid job_name"

after reviewing similar post host completion bash autocompletion: add description possible completions got right behaviour more or less. using - delimiter in job id query command

function _mycurrentjobs() {     local cur=${comp_words[comp_cword]}     local oldifs="$ifs"     local ifs=$'\n'     compreply=( $(compgen -w "$(bjobs -noheader -u $user \         -o "jobid job_name delimiter='-'")" -- $cur))     ifs="$oldifs"     if [[ ${#compreply[*]} -eq 1 ]];   #only 1 completion         compreply=( ${compreply[0]%%-*} )   #remove separator , after     fi     return 0 } complete -f _mycurrentjobs bkill bjobs bstatus bpeek bstop bresume

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
