Well i'm here because i need to modify a script while i'm doing many other admin tasks other than unix.
I'm still a newbie , i'm not an unix admin .
One does not have to be a 'unix admin' to address these questions.
Once again, please stick with the technical side of your question.
If you "have time" to discuss the merits of your post(s), please do so in the non-technical forums of this site.

i think it's the best way to search , and i don't see how i can do this with awk or sed.
Maybe shifting all the character on the left until the last then replace ?

i tried this with success :
sed '1,$ s/A$/B/g' oldfile > newfile
can i do in the same line the change of A to B and B to A ?
without doing :
sed '1,$ s/A$/B/g' oldfile > newfile1
sed '1,$ s/B$/A/g' oldfile > newfile2
cat newfile1 newfile2 newfile3

I have a space delimited text file with 1,000,000+ columns? I would only like to view specific ones (let's say through 1:10), how can I do that? Thanks! (3 Replies)
I have a space delimited text file where I want to replace all cells that are 0 with NA. However I cannot simply use 'sed/0/NA/g' because there are other 0's in the text file that are part of numbers.
Example input:
896.933464285715
0
874.691732142857
866.404660714286

What is the proper syntax to add specific text to a column in a file? Both the input and output below are tab-delineated. What if there are multiple text/fields, such as /CP&/2 /CM&/3 /AA&/4 Thank you :).

diffmk
diffmk(1) User Commands diffmk(1)NAME
diffmk - mark differences between versions of a troff input file
SYNOPSIS
diffmk oldfile newfile markedfile
DESCRIPTION
diffmk compares two versions of a file and creates a third version that includes "change mark" (.mc) commands for nroff(1) and troff(1).
oldfile and newfile are the old and new versions of the file. diffmk generates markedfile, which, contains the text from newfile with
troff(1) "change mark" requests (.mc) inserted where newfile differs from oldfile. When markedfile is formatted, changed or inserted text
is shown by | at the right margin of each line. The position of deleted text is shown by a single *.
USAGE
See largefile(5) for the description of the behavior of diffmk when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).
EXAMPLES
Example 1: An example of the diffmk command.
diffmk can also be used in conjunction with the proper troff requests to produce program listings with marked changes. In the following
command line:
example% diffmk old.c new.c marked.c ; nroff reqs marked.c | pr
the file reqs contains the following troff requests:
.pl 1
.ll 77
.nf
.eo
.nh
which eliminate page breaks, adjust the line length, set no-fill mode, ignore escape characters, and turn off hyphenation, respectively.
If the characters | and * are inappropriate, you might run markedfile through sed(1) to globally change them.
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |

Aesthetic considerations may dictate manual adjustment of some output. File differences involving only formatting requests may produce
undesirable output, that is, replacing .sp by .sp 2 will produce a "change mark" on the preceding or following line of output.
