table

[krava]

Hi,

How to delete everything and keep just numbers in this table?

xl_1=1.14653 xr_1=1.24653 yl_1=4.14801 yr_1=5.64801
xl_2=1.14653 xr_2=1.24653 yl_2=5.64801 yr_2=7.14801
xl_3=1.24653 xr_3=1.34653 yl_3=3.07031 yr_3=4.57031
xl_4=1.24653 xr_4=1.34653 yl_4=4.57031 yr_4=6.07031
xl_5=1.34653 xr_5=1.44653 yl_5=2.01758 yr_5=3.51758

Hi

To do exactly what you asked for :

awk '{gsub(/[^0-9]/,"")}1' /input/file

To do what probably you want :

awk '{for(i=1;i<=NF;i++)sub(/.*=/,"",$i)}1' /input/file

IMHO, sed is more suited:

sed 's![^ .0-9]*!!g' /path/to/input > outpout

Hope This Helps, PH.

OOps, disregard my previous post.

sed can still a good alternative if the pattern stays consistent.

sed 's/[a-z]\{2,\}_[0-9]\{1,\}=//g'

or even:

sed 's/.._[0-9]\{1,\}=//g'

OK, one another sed way:

sed 's![^ ]*=!!g' /path/to/input > outpout
