How do to wc command in if statement

There are other similar questions online out there, but I just couldn't figure out what's wrong with my code after trying those online suggestions. Below is my code:

LineNum = `wc -l <     /data/${INPUT:0:4}/${INPUT:4:2}/positions.$INPUT`
if [2 -le "$LineNum"] 
then
    echo ""
else
    awk 'NR!=1 {print $0}'     /data/${INPUT:0:4}/${INPUT:4:2}/positions.$INPUT | column -t
fi

So the $INPUT is in the format of YYYYMMDD, and I want the file to be displayed if the row count is more then a specific number. But I keep getting the error message "Command Not Found" for the if test.

Any suggestions is highly appreciated!

Solution

  • You are missing spaces around your condition. Try if [ 2 -le "$LineNum" ].
