Hello, i am new to the forum and know nothing about programing, Linux or Unix hope somebody can help me out.
I have a .txt file that i need to delete certain lines from. After searching the forum i noticed that using "sed" was the way to go, so i installed gnuwin32 (i use windows xp ) and started deleting lines with an specific value using this command:
Code:
sed /garbage/d inputfile > output
but now i would like to delete lines that fall into a certain category, for example lines with "more than 3 numbers" or "less than 4 characters".
This is a lot more complicated, or at least it seems that way to me, so if anyone knows how to do it i would appreciate the help, thanks.
I need some help deleting lines in a file that contain spaces. Im sure awk or sed will work but i dont know much about those commands. Any help is appreciated :D (7 Replies)

I have to programming a program in shell script which combine a lot of .txt files. But in all of these files the program had to delete the first both lines.

I have one base file, and multiple target files-- each have uniform line structure so no need to use grep to find things-- can just define sections by line number.
My question is quite simple-- can I use sed to copy a defined block of lines (say lines 5-10) from filename1.txt to overwrite an... (3 Replies)
Hi everyone,
I have two files (A and B) and want to combine them to one by always taking 10 rows from file A and subsequently 6 lines from file B. This process shall be repeated 40 times (file A = 400 lines; file B = 240 lines).
Does anybody have an idea how to do that using perl, awk or sed?... (6 Replies)
