: Use wget or the provided link to get big-zip-files.zip onto your local machine or the picoCTF webshell. Extract the archive : unzip big-zip-files.zip Use code with caution. Copied to clipboard
-r : Tells grep to search (look inside all folders and subfolders). "picoCTF" : The search string. . : Indicates the current directory. Flag Format 5 pjiczip
The most efficient way to solve this is by using the grep command, which allows you to search for specific text patterns across multiple files and subdirectories. : Use wget or the provided link to get big-zip-files
: The standard format for flags in this competition is picoCTF{...} . Use the following command to search recursively through all extracted files: grep -r "picoCTF" . Use code with caution. Copied to clipboard "picoCTF" : The search string
Once the command finishes, it will print the file path and the line containing the flag. It should look something like: ./some/long/path/file.txt:picoCTF{1_h0p3_y0u_us3d_gr3p_12345678}
