Remove trailing zeros
Hi I have a simple request but can't find the answer. I want to remove trailing zeros, and in some cases the fullstops, from the input data. Example of input file:

Code:
 
FR002_15.000_20.000
SD475_5.000_10.500
FG5647_12.250_15.500
BH2463_30.555_32.000

Desired output file would be:

Code:
 
FR002_15_20
SD475_5_10.5
FG5647_12.25_15.5
BH2463_30.555_32

Any suggestions with awk or sed, or perhaps perl would be greatly appreciated. Thanks in advance,
Theflamingmoe

if there are exactly three decimals then
Code:
 sed 's/.000//g'

will work.

Check this:
Code:
echo '171000'|sed 's/.000//g'
17

Hi,

Try this out,

Code:
sed 's/\.*00*$//' file

Code:
 sed 's/.000$//g' - Here there is no need for g modifier

will work.
@Ashik409: You have to consider the highlighted.

Cheers,

Try this:

Code:
sed 's/0*_/_/g;s/0*$//;s/\._/_/g;s/\.$//'

Could probably be done better, but it does the trick

Slight refinement to prevent unnecessary replacements:
Code:
awk -F_ '{for(i=1;i<=NF;i++){if(sub(/^[0-9]+\.[0-9]+$/,"&",$i)){sub(/0+$/,"",$i);sub(/\.$/,"",$i)}}}1' OFS=_ file

This will trim the zeroes only from the end of the lines.
