Command to find colums from the output
Hi
I want to know is there any command in Soalris which gives the number of columns for the output of any commnad. For example if I want to just check the number of columns from the generated output of uptime commnad, this must help me to find out.Of course we can check this from the man pages. But I am searching for a command. Thanks

There isn't a command that does this. You'll have to write a simple script.
For commands that return a bunch of lines you probably should try awk, this example will work for one-liners as well, but it's not efficient Code:
cols =`<command> | awk 'BEGIN {maxcol=0}
{ if (NF > maxcol)
{
maxcol=NF
}
} END {print maxcol} ' `
echo $cols
