I have a file with two columns (output from Tivoli Storage Manager) where each column has 13 character spaces and they are separated by 5 spaces. The columns are schedule names and node names and many of them are longer than 13 characters so they get hyphenated by TSM during the output. I want to undo the hyphenation to avoid losing part of the names when I need to grep out of the file later in the process. A small (somewhat fictionalised) sample of the data:
This does not display properly but both short lines (SOLS and ESS) are parts of the second column, not the first, and start at character 20.
My approach to this (for the second column) has been to find lines where the 31st character is a hyphen and try to replace the hyphen with the 20th to 30th characters from the next line. I've been trying to do this with sed (which I've never really used before) and what I've got so far looks like this:
with 'placeholder' standing in for 'something that finds the 20th to 30th characters from the next line and puts them where the hyphen is'. How do I do that part? Is this a workable approach at all? If not, then what should I be using instead?
Any help or suggestions would be much appreciated.

Hi,
How can I undo installation of a package on AIX 4.3 properly?
It's an install script. On linux, I usually just kill the process and delete from disk with this command "find .... exec rm -r {}\;". And it usually works. Can I do the same with AIX 4.3?
Thanks,

I generally use 'u' to do undo in vi editor. The problem is that it only does one level of undo.
Is it possible to recursively undo all the changes in vi editor till we reach the original stage. (2 Replies)

colrm
COLRM(1) BSD General Commands Manual COLRM(1)NAME
colrm -- remove columns from a file
SYNOPSIS
colrm [start [stop]]
DESCRIPTION
The colrm utility removes selected columns from the lines of a file. A column is defined as a single character in a line. Input is read
from the standard input. Output is written to the standard output.
If only the start column is specified, columns numbered less than the start column will be written. If both start and stop columns are spec-
ified, columns numbered less than the start column or greater than the stop column will be written. Column numbering starts with one, not
zero.
Tab characters increment the column count to the next multiple of eight. Backspace characters decrement the column count by one.
ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in environ(7).
EXIT STATUS
The colrm utility exits 0 on success, and >0 if an error occurs.
SEE ALSO awk(1), column(1), cut(1), paste(1)HISTORY
The colrm command appeared in 3.0BSD.
