I'd like to split a file into two, where the first file is the first two lines and the second is the remaining lines (third line to EOF).
View 2 Replieswhen I run the following command:
awk -F, '{print $10 "," $5 "," $1 "," $3 "," $4 "}' myfile > tmpfile
tmpfile displays the lines but they are all cut off and placed on the line below at the same point.
I need to grep a pattern which can be present in one line or could be split in 2 lines.Normal grep wont work in this case. Can anyone please help on this?There are 100's of files in which i need to search for this pattern so time is also a constrain.

View 5 Replies View Relatedstandard Linux installation utilities split the root file-system and the home file-system on two separate but relatively equal-sized partitions? For example, when I put fedora on an 80GB disk, it automatically gave the root file-system 32GB and home 30GB and the swap 8GB of space. However, since my home file-system has a directory with 28GB of files in it, why is my root file-system reading 100% usage? Is the home FS overlaid on top of the root FS? Is there an advantage to doing this? I just made a boot partition (50mb or so), a root partition (90% of the disk space) and a swap (4%-5% disk space).

I'm looking for a way to insert the number of lines in a file to the start of the aformentioned file. This should be simple but as I am not used to scripts in Linux, I am finding it tough going. I can find the number of lines in a file easily enough via
filesize=$(awk 'END {print NR}' $1)
but as for inserting this into the first line, i'm failing to do so. I've tried some of the other approaches on these forums but none so far have been able to do so.
I've tried:
sed '1i$filesize' $1
but sed i requires a string, not a variable so no go I've also tried:
mv "$1" "${1}.bak" 2>/dev/null || touch "${1}.bak"
cat $filesize "${1}.bak" >"$1"
but again with no luck as cat seems to need an input stream Just to recap, i want to insert a line at the start of a given file that holds the number of lines the original file has.
ie the file:
a
b
c
d
e
should become:
5
a
b
c

I'm trying to output two certain fields of a very large text file to 2 very small text files. Then take those files and add all the lines together to come up with a total from each file (two totals).
Here's what I've got:
Code:
#!/bin/bash
echo "0" > /media/in.txt
echo "0" > /media/out.txt
[code]....
Breakdown: Put 0 in a text file to be drawn by respective while loops for math later
Output last 60 integers to a file for total A (new integer every minute)
Output last 60 integers to a file for total B (new integer every minute)
The two while loops are supposed to be adding the lines together. The echo commands at the end are for testing purposes, just to see the output. However, when I run this, I get the output of
Code:
0 0
Which is obviously not what it's supposed to be. Is there a more efficient way to do this or am I missing something in the script that would reset the values to "0"?
