Grep float/integers but skip some integers
Hi,
I am working in bash in Mac OSX, I have following 'input.txt' file:

<INFO> HypoTestTool: >>> Done running HypoTestInverter on the workspace combined
<INFO> HypoTestTool: The computed upper limit is: 11 +/- 1.02651
<INFO> HypoTestTool: expected limit (median) 11
<INFO> HypoTestTool: expected limit (-1 sig) 9.84211
<INFO> HypoTestTool: expected limit (+1 sig) 11
<INFO> HypoTestTool: expected limit (-2 sig) 0.202636
<INFO> HypoTestTool: expected limit (+2 sig) 11

I want to grep all the integers and floats except -1 +1 -2 +2 before "sig".

I tried this
Code:
cat input.txt | grep -oE '\-?[0-9]+|\-?[0-9]+\.[0-9]+'

but i also get -1 +1 -2 +2 ,

I don't want to restrict the length of integers like this:
Code:
cat input.txt | grep -oE '\-?[0-9][0-9]|\-?[0-9]+\.[0-9]+'

Can you please help in it ?

This will only get the last integer on a line.
Code:
awk '$NF ~ /[0-9]/ { print $NF }' inputfile

Code:
grep -o '[^+-][0-9]\+[.]*[0-9]*' input.txt

THanks Corona688 and especially to Yoda,
I skip number before "+/-" if i use Corona's solution but Yoda's solution is suitable for me Smilie

How would you take care if any number is negative ? I mean if a number has minus sign then grep should print - sign with that number.

Thanks hanson,

But
Code:
$ grep -o '[+-]*[0-9]\+[.]*[0-9]* *$' input.txt

is skipping first number '11' before "+/-" , in output there should be 7 numbers.

Here's a possible way:
Code:
$ cat input.txt
<INFO> HypoTestTool: >>> Done running HypoTestInverter on the workspace combined
<INFO> HypoTestTool: The computed upper limit is: 11 +/- 1.02651
<INFO> HypoTestTool: expected limit (median) 11
<INFO> HypoTestTool: expected limit (-1 sig) -9.84211
<INFO> HypoTestTool: expected limit (+1 sig) 11
<INFO> HypoTestTool: expected limit (-2 sig) 0.202636
<INFO> HypoTestTool: expected limit (+2 sig) +11

Code:
$ grep -o '[+-]*[0-9]\+[.]*[0-9]*' input.txt | grep -v "[+-][12]\>"
11
1.02651
11
-9.84211
11
0.202636
+11
