[Bash] Remove everything after the first space in a string

Solved

Hello,

Beginner in Bash, I have a string stored in a variable.

For example: maVar="ceci 001 est un exemple 5600"

To remove a strict occurrence such as the ceci (including the space following the word ceci) from the string above, no problem, I do:
line1=${maVar#*ceci }

After this, I would now like to remove the space and everything that follows this space, after the pattern 001. Knowing that 001 is necessarily a group of digits but with a variable length (between 2 and 6 characters).

I tried by doing:
line2=${line1#* }

As well as other attempts, but I can’t get the desired result...

Any help is welcome :-)

Thanks in advance!

Configuration: Windows / Chrome 58.0.3029.110

    Problem solved after all...

    If it can help someone... 
    line2=$(echo $line1 | cut -d " " -f 1)


    So the truncated result of the variable is stored in $line2

    Hi,

    We can do this as well: 

    $ maVar="ceci 001 est un exemple 5600"

    $ echo "${maVar}"
    ceci 001 est un exemple 5600

    $ echo "${maVar#* }"
    001 est un exemple 5600

    $ echo "${maVar##* }"
    5600

    $ echo "${maVar% *}"
    ceci 001 est un exemple

    $ echo "${maVar%% *}"
    ceci
