Impossible condition - task10 about cicd-goat HOT 5 CLOSED

Hi @v3nd1g0, welcome and great to see you like to lab!
This shouldn't be a mistake, and it works for me. Have you tried running this command on this file and see what it returns?
Also, have you tried following the hints or solution and see if it works for you?

Hi @omer-cider. Thank you for your reply.
I have tested this expression in zshrc in such conditions:

• empty version file

$ > ./version
$ if [ $(wc -l <version) -eq 0 -a $(grep -Po "^\\d{1,2}\\.\\d{1,2}\\.\\d{1,2}$" version) ] ; then check2=true; else check2=false; fi && echo $check2
false

• version file with 1.0.13 (grep pattern ok)

$ echo "1.0.13" > ./version 
$ if [ $(wc -l <version) -eq 0 -a $(grep -Po "^\\d{1,2}\\.\\d{1,2}\\.\\d{1,2}$" version) ] ; then check2=true; else check2=false; fi && echo $check2
false

• version file with 100.1000.1000 (grep pattern no ok)

$ echo "1.100.100" > ./version 
$ if [ $(wc -l <version) -eq 0 -a $(grep -Po "^\\d{1,2}\\.\\d{1,2}\\.\\d{1,2}$" version) ] ; then check2=true; else check2=false; fi && echo $check2
false

In each case I have reached check2 == false.

What am I missing?
Thank you in advance.

P.S. I have checked writeup, but it doesn't work for me :c

Hi @v3nd1g0, wc -l <version counts the number of newlines. If you'll make sure to remove any \ns from the version file, the command will return true.

Thank you, you are right!
