Jul 7, 2010I have a series of input files formatted like this:
Code:
RTREVF, KOG3266 = 111
RTREVF, KOG3294 = 130
RTREVF, KOG3295 = 177
WAGF, KOG3307 = 107
JTTF, KOG3320 = 174
Each line represents a portion of a data matrix. I want to convert the numbers after the "=" to the range of that partition in the matrix such that the output file looks like this:
Code:
RTREVF, KOG3266 = 1-111
RTREVF, KOG3294 = 112-241
RTREVF, KOG3295 = 242-418
WAGF, KOG3307 = 419-525

Software :: Compare/diff A Range Of Lines From Two Text Files?
Mar 26, 2010i tried using diff --GTYPE-group-format= with <%, but not sure that right solution.Here's what im trying to do. I have two c source files, file1 and file2. file1 has a function in it that's been modified in file2. However, the functions begin at differnt line numbers in eachof the files. Is there a way to specify a range of file numbers on file1 and file2 to compare, using diff or any other combination of utilities? I can always output text from a range of lines from each file to two separate and new files and then compare those, but that's tedious. I could also write up a script to automate this type of solution, but I imagine there's an existing way of doing this.

General :: Compare File Timestamp In Bash?
May 6, 2010How do I compare the timestamp of two files? I tried this but it doesn't work:
file1time=`stat -c %Y fil1.txt`
file2time=`stat -c %Y file2.txt`
[code]....
I printed both the time stamps, in order and it gives me
1273143480
1254144394
./script.sh: line 13: [1273143480: command not found
So basically if comparision is not working, I guess. Or if there is any other nice way than what I am doing, please let me know.
Edit: There was no space in between if, so changing it to this works:
if [ $file1time -gt $file2time ]

General :: Script To Insert Number Of Lines In A File To The Start Of The File?
Sep 17, 2009I'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

General :: Adding Lines Of A File Together?
Feb 22, 2010I'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"?
