UNIX for Dummies Questions & Answers

Hi
I have a input file :::

1583904589034853904
1690234849023849023
159823890238409

The output file should have the record 16 appended to the record 15 and a variable should be added at a FIXED POSTION at 55.

The records are been processed inside a loop in a unix script.

Please help someone.

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

Maybe something like this:

Code:

$> cat infile
one
two
three
four
five
$> VAR=whatdoiknow; awk -v somevar=$VAR 'NR == 3 {o=$0; getline; print o,$0"                 "somevar; next} $0' infile
one
two
three four                 whatdoiknow

Hi

The variable appended should not depend on the lines which have been appended.The length of the line can vary and the variable should be at a fixed position.Also the 2 lines have been appended and I have to append a varible at a fixed postion.

For eq
Variable is 12345
And this has to appended to the line at postion 55.

The line is
1576789689789 1678978789787
15988789789789087 16778907097907
1589787870 167907907907907907

I have got till this point.Now I have to the variable at position 55 for each line.

Sorry for formatting.I am a new user.

New user, yes, but you still do not use CODE tags even I asked you too. Might want to read my former post with the paragraph about CODE tags.

Try with printf instead of print.
