hi...


i need to display the last line of the file and capture the line in to a variable in unix envt.(not the perl ones)... please help
# 2  
Code:
var=`tail -1 filename`
echo $var

# 3  
matrixmadhan got it right there is one more(from other so many)

Code:
var=`sed -n '$p' filename`
echo $var

# 4  
How's this:
Code:
while read line; do export var1="$line"; done < filename; echo $var1

If I'm not mistaken, no processes will be forked. Will work in ksh and bash.

Code:
var=`awk 'END{ print }' filename`
echo $var
