Dear all,

Is there any one can show me how to get a single line from a test file. What
command should I use and how?

Best Regards,
GY

using ksh:
read VARIABLE < testfile
or
VARIABLE=`line < testfile`

That's good for getting the FIRST line of the test file.  To get line 6
try:

  sed -n '6p' datafile

To get a the 4th line that doesn't have a # as the first char, try:

  sed -n  '/^[^#]/p' datafile |sed -n '4p'

It really depends on what you consider your "line" requirements.

Or in an awk you might do:

awk 'NR==6' testfile

(to get the 6th line)

If the $n variable contains the number of the line to be shown:
  n=8
  sed "${n}q;d"
or, hardwiring the line number:
  sed "8q;d"

This also works if $n is a regular expression contained in /s:
  n='/foo/'
  sed "${n}q;d"
or:
  sed '/foo/q;d'
