Keeping the number intact

Shell Programming and Scripting
1

Currently I have the following to separate the numeric values. However the decimal point get separated.

ls -lrt *smp*.cmd | awk '{print $NF}' | sed 's/^.*\///' | sed 's/\([0-9][0-9]*\)/ & /g'

As an example on the files

n02-z30-dsr65-terr0.50-dc0.05-4x3smp.cmd
n02-z30-dsr65-terr0.50-dc0.01-8x6smp.cmd
n02-z30-dsr65-terr0.50-dc0.006-8x6smp.cmd
n02-z30-dsr65-terr0.50-dc0.008-8x6smp.cmd

I am getting

n 02 -z 30 -dsr 65 -terr 0 . 50 -dc 0 . 05 - 4 x 3 smp.cmd
n 02 -z 30 -dsr 65 -terr 0 . 50 -dc 0 . 01 - 8 x 6 smp.cmd
n 02 -z 30 -dsr 65 -terr 0 . 50 -dc 0 . 006 - 8 x 6 smp.cmd
n 02 -z 30 -dsr 65 -terr 0 . 50 -dc 0 . 008 - 8 x 6 smp.cmd

I would like to have something like the following instead

 n 02 -z 30 -dsr 65 -terr 0.50 -dc 0.05 - 4 x 3 smp.cmd
n 02 -z 30 -dsr 65 -terr 0.50 -dc 0.01 - 8 x 6 smp.cmd
n 02 -z 30 -dsr 65 -terr 0.50 -dc 0.006 - 8 x 6 smp.cmd
n 02 -z 30 -dsr 65 -terr 0.50 -dc 0.008 - 8 x 6 smp.cmd

In this way the numbers are separated without detaching the decimal point.

Try:

ls -lrt *smp*.cmd | awk '{print $NF}' | sed 's/^.*\///' | sed 's/\([0-9][0-9.]*\)/ & /g'

@kristinu

sed 's/ \. /./' yourfile

Do you still have sorting issue with that list ?

$ echo 'n02-z30-dsr65-terr0.50-dc0.05-4x3smp.cmd' | sed 's/\([0-9][0-9]*[.]*[0-9]*\)/ & /g'
n 02 -z 30 -dsr 65 -terr 0.50 -dc 0.05 - 4 x 3 smp.cmd

Hi kristinu,

You may need the GNU version of 'sed' to use next command:

$ ... | sed 's/\([0-9]\+\(\.[0-9]\+\)\?\)/ \1 /g'
n 02 -z 30 -dsr 65 -terr 0.50 -dc 0.05 - 4 x 3 smp.cmd
n 02 -z 30 -dsr 65 -terr 0.50 -dc 0.01 - 8 x 6 smp.cmd
n 02 -z 30 -dsr 65 -terr 0.50 -dc 0.006 - 8 x 6 smp.cmd
n 02 -z 30 -dsr 65 -terr 0.50 -dc 0.008 - 8 x 6 smp.cmd

Not much now, just that having the complete number will make my life much easier, especially if I got to do a sort after.

add the dot in the list then :

... | sed 's/\([0-9][0-9.]*\)/ & /g'

Getting confused on the difference between the following two things

sed 's/\([0-9][0-9.]*\)/ & /g'
 sed 's/\([0-9][0-9]*[.]*[0-9]*\)/ & /g'

They both seem to work in my case. I tried on the files below

n02-z30-dsr65-terr11-dc0.05-4x3smp.cmd
n02-z30-dsr65-terr12.1-dc0.05-4x3smp.cmd
n02-z30-dsr65-terr123.12-dc0.05-4x3smp.cmd

When 2 solutions works, use the most simple one.

In case you get a version number like :

1.0.2.4

the first solution will still match it into 1 single matching , the second solution won't.

$ echo "1.0.2.4" | sed 's/\([0-9][0-9.]*\)/ & /g'
 1.0.2.4 
$ echo "1.0.2.4" | sed 's/\([0-9][0-9]*[.]*[0-9]*\)/ & /g'
 1.0 . 2.4

Just for a better display understanding :

$ echo "1.0.2.4" | sed 's/\([0-9][0-9.]*\)/_&_/g'
_1.0.2.4_
$ echo "1.0.2.4" | sed 's/\([0-9][0-9]*[.]*[0-9]*\)/_&_/g'
_1.0_._2.4_

So far in your file you don't have numeric string with multiple dot in it :
that is the reason why didn't you notice the difference.
