Which command for Label on Bash and Sh

Question

I would like to ask about command in Bash and Sh. On Cshell (.csh), I have use label and command "goto" as:

#!/bin/csh -f  

set a = 1      
goto CHECK     

CONT:   
    echo "${a}"
    exit

CHECK:
    if ( ${a} == 3 ) then
        exit
    else
        goto CONT
    endif

I make 2 label CONT and CHECK to separate code line. Other example:

 while (${lp_ct} < ${loop})
    START_ROUND:      
        set count = 1 
        echo "===================================================="
        bjobs | grep PEND | sort
        echo "----------------------------------------------------"
        echo "-- Round ${lp_ct}/${loop}"
        set pend_s = `bjobs | grep PEND | grep -wc AL_Vcs_s`
        if (${pend_s} > 4) then
            echo "You are pending more than 4 license on AL_Vcs_s"
            goto WAIT 
        endif         
        foreach job_pend (`bjobs | grep PEND | sort -r | awk '{print $1}'`)
            bswitch AL_Vcs_s $job_pend 
            if (${count} == ${no_sw}) then
                goto WAIT                                                                                                
            else      
            @ count = ${count} + 1
            goto SWITCH
            endif     
            WAIT:     
            echo "-- Round ${lp_ct}/${loop} finished!"
            echo "-- AL_Vcs   PEND/TOTAL: `bjobs|grep PEND|grep -wc AL_Vcs`/`bjobs -u all|grep PEND|grep AL_Vcs -wc`"
            echo "-- AL_Vcs_s PEND/TOTAL: `bjobs|grep PEND|grep -wc AL_Vcs_s`/`bjobs -u all|grep PEND|grep AL_Vcs_s -wc`"
            @ lp_ct = ${lp_ct} + 1
            goto END_ROUND
            SWITCH:   
        end           
        END_ROUND:    
            sleep 6m  
    end

There are any command to do this task on Bash and Sh?

Thank you so much.

It seems that Bash does not have goto or same instruction. You should try function instead, I think

@Quincy: in fact this _is_ an answer: POSIX shells and Bash have no `goto`s. – gniourf_gniourf Dec 28 '16 at 08:49
