afiedt.buf Tips

Oracle Database Tips by Donald BurlesonFebruary 21, 2015

Question:  What is the afiedt.buf file used for?  I see this afiedt.buf file in my OS, but I did not create an afiedt.buf file:

root> ls -alt|head

total 928228
drwxr-xr-x 21 oracle dba 2048 Sep 3 08:27 .
-rwxr-xr-x 1 oracle dba 55 Aug 22 11:56 afiedt.buf

Answer:  The name AFIEDT.BUF is short for Advanced Friendly Interface Editor Buffer.  In Oracle, the afiedt.buf file in the default editor in Oracle SQL*Plus. 

While most SQL*plus users will edit a "named" file, afiedt.buf is used when you type "edit" or "ed" in SQL*Plus without specifying a file name to hold the SQL*Plus commands.  Essentially, the afiedt.buf file is a default file location for holding SQL*Plus commands. 

As noted, it is better to use a named file rather than the afiedt.buf file.  You create named files in SQL*Plus as follows, using the "host" command:

Windows:       host notepad myfile.sql

UNIX/Linux   !vi myfile.sql   <== The "bang (!) is equal to the "host" command
