Replace col 23 - 26 with new value, non delimited file
hello,
i have a undelimited file which contains 229 byte records. i want to change column 23 - 26 with a new value and also change the sign of the data in colulmn 30 - 70. i've tried SED for the first change, but nothing happens:
Code:
sed 's/\(^.\{22\}\).\{4\}\(.*\)/\0603\2/' inputfile

heres an example of my record -but it doesn't display the whole 229 bytes - not sure why
Code:

Please give us a few lines from inputfile and provide the desired output as well. It isn't obvious whether you're asking us to change a + to a - and a - to a + or if you want us to insert or remove a -. We also need to see if you're counting from 0 or from 1.

---------- Post updated at 15:13 ---------- Previous update was at 14:30 ----------

Try:
Code:
sed -n 's/\(^.\{22\}\)..../\10603/
s/\(^.\{29\}\)\( *\)-/\1\2s/
s/\(^.\{29\}\)\( *\)[ +]\([0-9.]\)/\1\2-\3/
s/\(^.\{29\}\)\( *\)s/\1\2 /
p' inputfile

i'm getting an error saying command garbled:
sed: command garbled: s/\(^.\{22\}\)..../\10603/s/\(^.\{29\}\)\( *\)-/\1\2s/s/\(^.\{29\}\)\( *\)[ +]\([0-9.]\)/\1\2-\3/s/\(^.\{29\}\)\( *\)s/\1\2 /p

i really need to concentrate on the second change - getting the amount column to be flipped from neg to pos and pos to neg = thanks!

It looks like you pasted everything into 1 line instead of keeping the five lines I posted.

If you insist on making it a single line, you can try:
Code:
sed -n 's/\(^.\{22\}\)..../\10603/;s/\(^.\{29\}\)\( *\)-/\1\2s/;s/\(^.\{29\}\)\( *\)[ +]\([0-9.]\)/\1\2-\3/;s/\(^.\{29\}\)\( *\)s/\1\2 /;p' inputfile

but I MUCH prefer code where I can more easily see the relationship between the changes made by the last three substitute commands than having something that hides those relationships on a single line.

Both of them produce the output:
Code:
99999999999999930531130603AUD                        -176938000.000000                                                 S1HHHHHHH079928    ST HHHHHHH079928

with the sed on OS X with the latest update to your input. In addition to changing a - to a space and a space to a - in the last column before the first digit in that field, it will also change a + to a - in that position. This should work with any sed utility that conforms to the POSIX standards and the Single UNIX Specification.

obviously, i dont know what i am doing. when i execute that command; it just displays the output on the screen as it runs thru each record, but doens't make the changes to the file?
# 6  
Old 05-31-2013
You never said you wanted to store the changes in your original file and your original sed command made no attempt to save the changes.

To do that, you could try:
Code:
sed -n 's/\(^.\{22\}\)..../\10603/
s/\(^.\{29\}\)\( *\)-/\1\2s/
s/\(^.\{29\}\)\( *\)[ +]\([0-9.]\)/\1\2-\3/
s/\(^.\{29\}\)\( *\)s/\1\2 /
p' inputfile > tmp$$ && cp tmp$$ inputfile && rm tmp$$
