Question Delete last characters in each column

I need to delete the last 11 characters from each number and they are all in the same line (each is in a different column):

Code:
-6.89080901827020800000 3.49348891708562325136 1.47988367839905286876 -2.29707635413510400000 -3.49342364708562325136 -4.43758473239905286876 -2.29707635413510400000 .00003263500000000000 -1.47885052700000000000 -6.89080901827020800000 .00003263500000000000 -4.43758473239905286876

If I use:
Code:
sed '$s/...........$//'
    or
awk ' sub( "............$", "")'

They only delete from the last field. It seems simple but I couldn't find answer and can't figure it out, please help. Smilie

Code:
awk '{for(i=1;i<=NF;i++) sub(/...........$/,X,$i)}1' file

Thanks it works perfectly Smilie

Can you explain what is that X for and why there is a 1 in the end of the command??

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

I was trying to set and use the OFMT variable (as you obviously want to modify long mantissae), but this did not work in my linux/mawk system - no idea why not!

Or, sed:
Code:
sed -r 's/.{11}( |$)/\1/g' file
-6.890809018 3.493488917 1.479883678 -2.297076354 -3.493423647 -4.437584732 -2.297076354 .000032635 -1.478850527 -6.890809018 .000032635 -4.437584732

X is nothing but an undefined variable. So substituting with X is same as substituting with null.

1 == true and 0 == false. When true, the default awk action is to print the record. So that 1 is just to force awk to print the whole record after performing substitution.

Perhaps you were looking for CONVFMT ?
Code:
awk '{for(i=1; i<=NF; i++) $i+=0}1' CONVFMT="%.10f" file

Output:
Code:
-6.8908090183 3.4934889171 1.4798836784 -2.2970763541 -3.4934236471 -4.4375847324 -2.2970763541 0.0000326350 -1.4788505270 -6.8908090183 0.0000326350 -4.4375847324

Thanks, yes. I knew something was there but I was not scrutinizing the man page carefully enough... Anyhow, does not really beautify/curtail the code...
