awk - Rename output file, after processing, same as input file
I have one input file ABC.txt and one output DEF.txt. After the ABC is processed and created output, I want to rename ABC.txt to ABC.orig and DEF to ABC.txt. Currently when I am doing this, it does not process the input file as it cannot read and write to the same file. How can I achieve this?

Is it possible if I can put a time interval between the awk script and mv commands??

This would resolve my issue.


Example:

Code:
awk ' $1=="01" { print $2 $4}' ABC.txt > DEF.txt
mv ABC.txt ABC.orig
mv DEF.txt ABC.txt

ABC.txt
Code:
01  03  03  04

DEF.txt
Code:
01  08  AA FA

tokens

TOKENS(1)						       AFS Command Reference							 TOKENS(1)

NAME

       tokens, tokens.krb - Displays the issuer's tokens

SYNOPSIS

       tokens [-help]

       tokens [-h]

       tokens.krb [-help]

       tokens.krb [-h]

DESCRIPTION

       The tokens command displays all tokens (tickets) cached on the local machine for the issuer. AFS server processes require that their
       clients present a token as evidence that they have authenticated in the server's local cell.

       The (mostly obsolete) tokens.krb command is the same as tokens except that it also displays the user's Kerberos v4 ticket cache.

OPTIONS

       -help
	   Prints the online help for this command. All other valid options are ignored.

OUTPUT

       The output lists one token for each cell in which the user is authenticated. The output indicates the

       o User's AFS UID, if it is available for display.

       o Server for which the token is valid (normally, afs).  This includes a cell specification.

       o Day and time the token expires.

       The output of the Kerberos version of this command, tokens.krb, also reports the following about the Kerberos ticket-granting ticket: the
       ticket owner, which Kerberos ticket-granting service that issued the ticket (for example, "krbtgt.ABC.COM"), and ticket's expiration date.

       The string "--End of list--" appears at the end of the output. If the user is not authenticated in any cell, this line is all that appears.

EXAMPLES

       The following example shows the output when the issuer is not authenticated in any cell.

	  % tokens
	  Tokens held by the Cache Manager:

	     --End of list--

       The following example shows the output when the issuer is authenticated in ABC Corporation cell, where he or she has AFS UID 1000.

	  % tokens
	  Tokens held by the Cache Manager:

	  User's (AFS ID 1000) tokens for afs@abc.com [Expires Jan 2 10:00]
	     --End of list--

       The following example shows the output when the issuer is authenticated in the ABC Corporation cell, the State University cell, and the XYZ
       Company cell. The user has different AFS UIDs in the three cells. Tokens for last cell are expired:

	  % tokens
	  Tokens held by the Cache Manager:

	  User's (AFS ID 1000) tokens for afs@abc.com [Expires Jan 3 10:00]
	  User's (AFS ID 4286) tokens for afs@stateu.edu [Expires Jan 3 1:34]
	  User's (AFS ID 22) tokens for afs@xyz.com [>>Expired<]
	     --End of list--

       The following example shows the output when the issuer uses the tokens.krb version of the command after authenticating in the ABC
       Corporation cell using the klog.krb command.

	  % tokens.krb
	  Tokens held by the Cache Manager:

	  User's (AFS ID 1000) tokens for afs@abc.com [Expires Jan 31 00:09]
	  User smiths tokens for krbtgt.ABC.COM@abc.com [Expires Jan 31 00:09]
	     --End of list--
