Inaccessible UNIX filenames…

Richard Evans Richard Evans Profile: Richard Evans

I goofed up earlier and somehow managed to give my file a name. To fix this I was able to rename it by using ctl+v followed by ctl+h to generate the ^H character.

The Problem

When I saved it in vi I somehow messed up my :wq! And I it saved it with this name:


"^H" [New file] 167 lines, 3054 characters

You can see below that there is a file with no filename.


[oracle: /oracle/DB/102_64/network/admin] ls -al

The Fix

By using the ctl+v followed by ctl+h I was able to reproduce the ^H character and get the file information.


[oracle: /oracle/DB/102_64/network/admin] ls -al ^H
-rw-r--r-- 1 oracle dba 3054 Jun 17 11:12

Now I move it to a file with a legit name…


[oracle: /oracle/DB/102_64/network/admin] mv ^H test

Now I can move it to something useful :-)
