[Solved] What could be the substitute to handle the flow control of go-to in SHELL script [duplicate]

by


Rather than trying to extend the syntax of the shell to do

start:

for ...; do
    for ...; do
        ...
    done
done

if CONDITION; then
    goto start
else
    SOMETHING
fi

you may do

while true; do
    for ...; do
        for ...; do
            ...
        done
    done

    if ! CONDITION; then
        SOMETHING
        break
    fi
done

or

while true; do
    for ...; do
        for ...; do
            ...
        done
    done

    if ! CONDITION; then
        break
    fi
done

SOMETHING

UPDATE: New code in question:

start:
while true; do
    for ...; do
        for ...; do
            if ...; then
                break 99
            fi
            ...
        done
    done
done

...

if CONDITION; then
    SOMETHING
    goto start
else
    SOMETHING_ELSE
fi

for ...; do
    ...
done

To avoid a goto, this may be transformed into

while true; do
    while true; do
        for ...; do
            for ...; do
                if ...; then
                    break 99   # change to one less than
                               # the total depth, to not exit
                               # outermost loop
                fi
                ...
            done
        done
    done

    ...

    if ! CONDITION; then
        break
    fi

    SOMETHING
done

SOMETHING_ELSE

for ...; do
    ...
done
