## WriteupWhen looking at the file, we see a bunch of gibberish bash. I did some researchand found a way to "debug" a script in bash.
The command is simple:```bash -x <program>```
After running this, we see all commands ran in bash. We can do some parsingthrough this debug output and retrieve:```+++ printf %s e+++ printf %s c+++ printf %s h+++ printf %s o+++ printf %s ' '+++ printf %s d+++ printf %s o+++ printf %s n+++ printf %s t+++ printf %s ' '+++ printf %s j+++ printf %s u+++ printf %s s+++ printf %s t+++ printf %s ' '+++ printf %s r+++ printf %s u+++ printf %s n+++ printf %s ' '+++ printf %s i+++ printf %s t+++ printf %s ,+++ printf %s ' '+++ printf %s d+++ printf %s u+++ printf %s m+++ printf %s m+++ printf %s y+++ printf %s ' '+++ printf %s #+++ printf %s ' '+++ printf %s f+++ printf %s l+++ printf %s a+++ printf %s g+++ printf %s {+++ printf %s u+++ printf %s s+++ printf %s 3+++ printf %s _+++ printf %s z+++ printf %s s+++ printf %s h+++ printf %s ,+++ printf %s _+++ printf %s d+++ printf %s u+++ printf %s m+++ printf %s m+++ printf %s y+++ printf %s }```
Evaluating to:```dont just run it, dummy # flag{us3_zsh,_dummy}```
## Flagflag{us3_zsh,_dummy}
