Hi masters,
I have one doubt,
lets's say file1 has the following contents,
1
2.0
3.1
5.5
7
5.10
5.9
How to sort these contents to get the o/p like
1
2.0
3.1
5.5
5.9
5.10
7
Note:5.10 should come after 5.9.
Please provide your comments.
Thank you
sort -t '.' -k1,1 -k2,2 -n myFile
I get an error with the code of vgersh99, try:
sort -t '.' -k 1,1n -k 2,2n file
strange - works fine under Solaris9.
you can try - not sure the order matters:
sort -t '.' -n -k1,1 -k2,2 myFile
A quick observation - neither of these solutions work for non-trivial floating point numbers, because the order of the most significant digit is the reverse on the right of the decimal point as compared to the left.
So, while 1034 < 10034 is true; 0.1034 < 0.10034 isn't.
An example is below:
$
$
$ cat f0
1
2.0
2.01
3.1
5.10034
5.5
7
5.10
5.1034
5.9
$
$ sort -t"." -k1,1n -k2,2n f0
1
2.0
2.01
3.1
5.5
5.9
5.10
5.1034
5.10034
7
$
$
Note that the floating point numbers in red are not in ascending order.
I am sure will be something for this in the shell itself, but here's a simple Perl solution:
$
$ cat f0
1
2.0
2.01
3.1
5.10034
5.5
7
5.10
5.1034
5.9
$
$ perl -lne 'chomp; push @x, $_; END {print foreach sort @x}' f0
1
2.0
2.01
3.1
5.10
5.10034
5.1034
5.5
5.9
7
$
$
tyler_durden
$ cat file
1
2.0
2.01
3.1
5.10034
5.5
7
5.10
5.1034
5.9
$ sort -kn1 file
1
2.0
2.01
3.1
5.10
5.10034
5.1034
5.5
5.9
7
I got the error with a HP-UX on my work but it works fine on my Debian system.
anbu23 and durden_tyler, the second column must be also sorted in numeric order so the output should be like:
3.1
5.5
5.9
5.10
5.1034
5.10034
7
I didnt read the requirements properly.
That's right; my bad... gotta read those requirements carefully.
