11 – grep 1

Solve

Can you find the flag in file? This would be really obnoxious to look through by hand, see if you can find a faster way. You can also find the file in /problems/grep-1_0_c0c0c16438cdbee39591397e16389f59 on the shell server.

Solution

Goto directory

cd /problems/grep-1_0_c0c0c16438cdbee39591397e16389f59

See what’s in there

ls

returned with “file”

cat file | grep pico

answer

picoCTF{grep_and_you_will_find_52e63a9f}
