+```
+$ find / -user flag00 2>/dev/null
+
+...output (only 2 lines) 👉 and we want to cat them all out
+
+$ find / -user flag00 -exec cat {} + 2>/dev/null
+
+cdiiddwpgswtgt 👉 looks like cipher
+```
+- explain
+    - `/` - from root directory
+    - `+` - forces `find` to run `cat` on many files at once and not one at a time
+    - `2>/dev/null` - redir stderr output to `/dev/null`
+- solve the cipher
+```
+a = ord('a')
+for i in range(25):
+    print(i, ''.join(chr(a + (ord(c) - a + i) % 26) for c in 'cdiiddwpgswtgt'))
+```
+- swicth to user `flag00` using the pw
+```sh
+$ su flag00
+$ Password: nottoohardhere
+$ getflag 
+```
+# Level 00 - token
