hi all ,
my file looks something like this..

time typ min max
6 9697nS 1.7997V 1.6486V 1.9499V
7.2727nS 1.7997V 1.6488V 1.9499V
7.5758nS 1.7998V 1.6489V 1.9499V
7.8788nS 1.7998V 1.6491V 1.9499V
8.1818nS 1.7998V 1.6492V 1.9499V
8.4848nS 1.7998V 1.6493V 1.9499V
8.7879nS 1.7999V 1.6494V 1.9500V
9.0909nS 1.7999V 1.6494V 1.9500V
9.3939nS 1.7999V 1.6495V 1.9500V
9.6970nS 1.7999V 1.6496V 1.9500V
10.0000nS 1.7999V 1.6496V 1.9500V
10.3030nS 1.7999V 1.6497V 1.9500V

i need a simple perl or awk script that would give the time stamp at which all the three typ min and max values match...

eg.output something like this
8.7879nS 1.7999V 1.6494V 1.9500V
9.0909nS 1.7999V 1.6494V 1.9500V
9.6970nS 1.7999V 1.6496V 1.9500V
10.0000nS 1.7999V 1.6496V 1.9500V

thanks

if you want all 3 to match, why do you have

9.6970nS 1.7999V 1.6496V 1.9500V
10.0000nS 1.7999V 1.6496V 1.9500V

on the list? The middle value doesn't match.

anyway, try

grep "<value1> <value2> <value3>" <filename>

e.g.

grep "1.7999V 1.6494V 1.9500V" ****

i guess you haven't understood what i meant...

i need the time stamps at which the typ min and max values of two or more consecutve rows have the same typ min values..
9.6970nS 1.7999V 1.6496V 1.9500V
10.0000nS 1.7999V 1.6496V 1.9500V
like the one here since the time 9.6970nS and 10.000ns have the same values in their typ min max column.
i can delete one of them....

so i need a script that would give the time values at which the redundancy of all the three with the previous time occurs....

Hi.

This can be done with standard commands:

#!/usr/bin/env bash

# @(#) s1       Eliminating consecutive lines with duplicate character fields.

echo
set +o nounset
LC_ALL=C ; LANG=C ; export LC_ALL LANG
echo "Environment: LC_ALL = $LC_ALL, LANG = $LANG"
echo "(Versions displayed with local utility \"version\")"
version >/dev/null 2>&1 && version "=o" $(_eat $0 $1) grep uniq
set -o nounset
echo

FILE=${1-data1}

echo " Data file $FILE:"
cat $FILE

# Keep lines beginning with numeric, remove duplicates with
# identical strings in fields 2-end of line.

echo
echo " Results:"
grep '^[0-9]' $FILE |
uniq --skip-fields=1

exit 0

Producing:

% ./s1

Environment: LC_ALL = C, LANG = C
(Versions displayed with local utility "version")
OS, ker|rel, machine: Linux, 2.6.11-x1, i686
Distribution        : Xandros Desktop 3.0.3 Business
GNU bash 2.05b.0
grep (GNU grep) 2.5.1
uniq (coreutils) 5.2.1

See man grep and man uniq for details ... cheers, drl

Hi.

In reviewing your other recent posts, and considering your request for such a particular solution, it looks like you are posting coursework questions.

If so, you need to be aware that such questions are not allowed here -- see http://www.linuxforums.org/forum/lin...ums-rules.html
