i currently have a file with columns similar to this
customer name owed
CID123 John 300
CID342 harry 500
at present i use use awk to find the amount owed by the customer using the customer ID (CID).
if the customer spends more money how would i go about using sed/awk etc to modify the amount they owe? (all the arithmetic is already working, i just need to know how to append the new value to the file under the owed column for the correct customer)
This might be a lame answer, but here it goes:
You can save each column into arrays
For corresponding CID*** of array1[i] u'll easily get array3[i] which simplifies your arithmatic part. You can make the updates or changes in owed i.e array3 and then rewrite the whole file using these updated arrays.
There might be a much simpler solution i.e. updating only the ones that have changed, this is what i would have done

Hi,
I'm attempting to rename some files that have spaces in them. Without linking sed commands together is it possible to replace the first three "." to " ".
File.name.is.long.ext -> File name is long.ext
I can get the desired effect with

DESCRIPTION
This tunable determines the type of pipe that is created by the system call. If set to the default value of zero, all pipes created by are
normal HP-UX file-system pipes. If the value is non-zero, creates STREAMS-based pipes, and STREAMS modules can be pushed onto the result-
ing stream.
If this tunable is set to a non-zero value, the and module and driver must be configured in file
Who Is Expected to Change This Tunable?
Any customer.
Restrictions on Changing
Changes to this tunable take effect at next reboot.
When Should the Tunable Be Turned On?
If the customer uses applications that require STREAMS-based pipes, this tunable should be turned on.
What Are the Side Effects of Turning the Tunable On?
STREAMS-based pipes performance may differ from normal file system pipes.
When Should the Tunable Be Turned Off?
If the customer does not need the STREAMS-based pipes, this tunable should be turned off.
What Are the Side Effects of Turning the Tunable Off?
Applications that try to push STREAMS modules onto the pipe will fail.
What Other Tunable Should Be Changed at the Same Time as This One?
If this tunable is set to a non-zero value, the and module and driver must be configured in the file
