Hello. I just found out about awk, and it appears that this could handle the problem I'm having right now.
I first stumbled on the thread How to extract first and last line of different record from a file, and that problem is almost similar to mine.
In my case, an ASCII file will contain the... (0 Replies)

The awk needed....if coloumn 9 == i (coloumn 9 is string ), output the sum of x's(coloumn 22 ) in all records and sum of y's (coloumn 23 ) in all records in a file (records.txt).... (6 Replies)
Can anyone tell me how sum values in each record of a file and append that value to the end? For instance a typical record will be:
FY12,Budget,771100,,,,,,,,,250,-250
I'd like the record to become
FY12,Budget,771100,,,,,,,,,250,-250,0
which can be put into another file.
Thank you. (6 Replies)

I was just curious about how to sum the total file size of a certain type of file. For instance:
$find . -name "*.aif"
will print out the paths to each .aif file. Instead of printing, how could one sum the total space used by all of the aif files? Thanks!

I was playing around to see how stuff works, and was trying to sum all fields in a file.
cat file
1 2 3 4
5 6 7 8
9 10 11 12
I made this script:
awk 'BEGIN {OFS=RS}{$1=$1}{s+=$0} END {print "sum="s}' file
This gives 15, why not 78?
I test it like this

nfsidmap(5) File Formats Manual nfsidmap(5)NAME
nfsidmap - The NFS idmapper upcall program
SYNOPSIS
nfsidmap [-v] [-t timeout] key desc
nfsidmap [-v] [-c]
nfsidmap [-v] [-u|-g|-r user]
DESCRIPTION
The file /usr/sbin/nfsidmap is used by the NFS idmapper to translate user and group ids into names, and to translate user and group names
into ids. Idmapper uses request-key to perform the upcall and cache the result. /usr/sbin/nfsidmap is called by /sbin/request-key, and
will perform the translation and initialize a key with the resulting information.
nfsidmap can also used to clear the keyring of all the keys or revoke one particular key. This is useful when the id mappings have failed
to due to a lookup error resulting in all the cached uids/gids to be set to the user id nobody.
OPTIONS -c Clear the keyring of all the keys.
-g user
Revoke the gid key of the given user.
-r user
Revoke both the uid and gid key of the given user.
-t timeout
Set the expiration timer, in seconds, on the key. The default is 600 seconds (10 mins).
-u user
Revoke the uid key of the given user.
-v Increases the verbosity of the output to syslog (can be specified multiple times).
CONFIGURING
The file /etc/request-key.conf will need to be modified so /sbin/request-key can properly direct the upcall. The following line should be
added before a call to keyctl negate:
create id_resolver * * /usr/sbin/nfsidmap -t 600 %k %d
This will direct all id_resolver requests to the program /usr/sbin/nfsidmap. The -t 600 defines how many seconds into the future the key
will expire. This is an optional parameter for /usr/sbin/nfsidmap and will default to 600 seconds when not specified.
The idmapper system uses four key descriptions:
uid: Find the UID for the given user
gid: Find the GID for the given group
user: Find the user name for the given UID
group: Find the group name for the given GID
You can choose to handle any of these individually, rather than using the generic upcall program. If you would like to use your own pro-
gram for a uid lookup then you would edit your request-key.conf so it looks similar to this:
create id_resolver uid:* * /some/other/program %k %d
create id_resolver * * /usr/sbin/nfsidmap %k %d
Notice that the new line was added above the line for the generic program. request-key will find the first matching line and run the cor-
responding program. In this case, /some/other/program will handle all uid lookups, and /usr/sbin/nfsidmap will handle gid, user, and group
lookups.
