sed for all columns
Hi,

I would like to know how can I use sed in all columns of a file tab separated.

Example of input file:
Code:
0/0:0:1,0,0  0/2:0:0,2,0

Desired output file:
Code:
1,0 0,2

You need to remember to use CODE tags and you need to clearly describe the edits that you are trying to make to your file using sed. Note that neither of your tab separated sample files contain any tabs.

With sed, try:
Code:
sed 's/[^:]*:[^:]*:\([^,]*,[^,]*\)/\1 /g; s/ [^ ]*$//'  file

--
Alternatively with awk:
Code:
awk '{for(i=1; i<=NF; i++) {sub(/.*:/,x,$i); sub(/,[^,]*$/,x,$i)}}1'  file

or
Code:
awk '{for(i=1; i<=NF; i++) {split($i,F,"[/:,]"); $i=F[4]","F[5]}}1' file

Got Perl?
Code:
perl -nle '@m = /:(\d,\d)/g and print "@m"' file
