Hi I have ubuntu server 12.04 running a pureftpd server. Whenever I donwload files from the sevrer it adds a extra line between every line. Like this...
Line one
(Blank line)
Line two
(Blank line)
Line three
(Blank line) = blank line
Its really irritating in html documents but when doing this with pictures, it breaks them and they cannot be read correctly.
Any ideas?
Thanks
Hi,
I'm trying to read a line and the next line in a shell script by executing the following code:
Code:
for i in `seq 1 $numLines`; do
line=$(sed -n '{$i}p' outputFile)
echo $line
done
$numLines contanis the outputFile's number of lines.
It doesn't work and I cannot use a while loop because I need to reed $(i+1) line after $i line.
I have a log-file where at the end of a series of lines you can see if this block is relevant
now I'm looking for a command like sed to delete de blocks ending with "Content-Length: 0" and beginning with the last "--" before this line.
I tried sed -n "/--/,/Content-Length: 0/d" but this takes the first "--" and the first "Content-Length: 0" and deletes it.
ex :
line 1 "--"
line 2
line 3 "
Add a line in a specific position with Linux
If you need to add a line to a file in Linux, and you need to add that line in a specific position of the file there is an easy solution, even if you need to do it to hundreds of thousands of files.
Consider this file:
line 1
line 2
line 4
As you can see we missed line 3, so to add it just execute this command:
sed '3iline 3'

{line2}(field 1
I have a large file which contains tables of different tab separated data. The different tables are separated by a blank line.
I have the line number of the start of a particular table and I need to retrieve the whole table.
How can I use grep (or something similar) to get the line number of the next blank line after a specific line number?
