Find time difference between two consecutive lines in same file.
Hello
I have a file in following format:
IV 08:09:07
NM 08:12:01
IC 08:12:00
MN 08:14:20
NM 08:14:15
I need a script to compare time on each line with previous line and show the inconsecutive line. Ex.:
08:12:00
08:14:15
A better way will be a message in this form:
“IC has 1 second difference on 08:12:00 time
NM has 5 second difference on 08:14:15 time”
But first example will be more than enough.
How i can compare each line whit previews line? I tried this script:
Code:
cat myfile|gawk '{print $2}'>tempfile
while read line
do
PAST=$line -1 ****** someheting similar here
DIFF=$(($PAST-$LINE))
echo $line $DIFF
done<tempfile
but it doesn’t work in line 3. Is a syntax problem or is an impossible command. I don’t know. I’m new in this. I even try to make a variable name, variable but again I’m stuck in line 3 on syntax or in “impossibliness” problem:
Code:
while read line ;do
for (( i = 1 ; i <= 5; i++ ))
PAST${!i}=$line **********!!!????
DIFF=$(($PAST${!i}-$(($PAST${!i-1}))
echo $DIFF
done
done < tempfile
It must be an “eval” expression somewhere but “indirect variable reference” is way over my head right now. I have a felling that all can be done very easily but I can’t see how .
Thanks in advance for your time.

diff
DIFF(1) General Commands Manual DIFF(1)NAME
diff - differential file comparator
SYNOPSIS
diff [ -efbh ] file1 file2
DESCRIPTION
Diff tells what lines must be changed in two files to bring them into agreement. If file1 (file2) is `-', the standard input is used. If
file1 (file2) is a directory, then a file in that directory whose file-name is the same as the file-name of file2 (file1) is used. The
normal output contains lines of these forms:
n1 a n3,n4
n1,n2 d n3
n1,n2 c n3,n4
These lines resemble ed commands to convert file1 into file2. The numbers after the letters pertain to file2. In fact, by exchanging `a'
for `d' and reading backward one may ascertain equally how to convert file2 into file1. As in ed, identical pairs where n1 = n2 or n3 = n4
are abbreviated as a single number.
Following each of these lines come all the lines that are affected in the first file flagged by `<', then all the lines that are affected
in the second file flagged by `>'.
The -b option causes trailing blanks (spaces and tabs) to be ignored and other strings of blanks to compare equal.
The -e option produces a script of a, c and d commands for the editor ed, which will recreate file2 from file1. The -f option produces a
similar script, not useful with ed, in the opposite order. In connection with -e, the following shell program may help maintain multiple
versions of a file. Only an ancestral file ($1) and a chain of version-to-version ed scripts ($2,$3,...) made by diff need be on hand. A
`latest version' appears on the standard output.
(shift; cat $*; echo '1,$p') | ed - $1
Except in rare circumstances, diff finds a smallest sufficient set of file differences.
Option -h does a fast, half-hearted job. It works only when changed stretches are short and well separated, but does work on files of
unlimited length. Options -e and -f are unavailable with -h.
FILES
/tmp/d?????
/usr/lib/diffh for -h
SEE ALSO cmp(1), comm(1), ed(1)DIAGNOSTICS
Exit status is 0 for no differences, 1 for some, 2 for trouble.
BUGS
Editing scripts produced under the -e or -f option are naive about creating lines consisting of a single `.'.
