I have wrote a code to essentially to scan line by line and extract the epoch time and count value. I was able to compare the line time with current time and make an if condition statement to increase count but I m having problems replacing the old count with the new count value. I know sed looks like the obvious choice but i cant seem to get it to work and as far as I know all sed's output go to a file not the same line...
Code:
for line in `cat Final`
do
echo -e "$line"
count=`echo $line | cut -d ',' -f 4`
etime=`echo $line | cut -d "," -f 1`
echo $etime
echo $count
sytime=`date +%s`
dif=$(( $sytime - $etime ))
echo $dif
if [ $dif -ge 900 ];then
echo true
newcount=$(( $count + 1 ))
tline= sed s/"$count"/"$newcount"/ $line
$line = $tline
echo $newcount
echo $line
else
echo flase
fi
done
Its a Bash Script

Hi
I have a case where I am grabbing patterns and subsequent lines using
sed -n -e '/regex/{$!N;p;}'
This returns just the regex line when it is the last line of my file.
Now I may have even number of lines in some cases (regex never at end) and odd in very rare cases.
If the line... (6 Replies)

what is the difference b/w
1) #define TI_ZN (1 << 1)
#define TI_ZN (1 << 2)
and
2) #define TI_ZN 2
#define TI_ZN 4
Instead of using left shift we can assign the value 2 directly?
Or there is a reason behind this to use shift operator?... (4 Replies)

RATFOR(1) General Commands Manual RATFOR(1)NAME
ratfor - rational Fortran dialect
SYNOPSIS
ratfor [ option ... ] [ filename ... ]
DESCRIPTION
Ratfor converts a rational dialect of Fortran into ordinary irrational Fortran. Ratfor provides control flow constructs essentially iden-
tical to those in C:
statement grouping:
{ statement; statement; statement }
decision-making:
if (condition) statement [ else statement ]
switch (integer value) {
case integer: statement
...
[ default: ] statement
}
loops: while (condition) statement
for (expression; condition; expression) statement
do limits statement
repeat statement [ until (condition) ]
break [n]
next [n]
and some syntactic sugar to make programs easier to read and write:
free form input:
multiple statements/line; automatic continuation
comments:
# this is a comment
translation of relationals:
>, >=, etc., become .GT., .GE., etc.
return (expression)
returns expression to caller from function
define:
define name replacement
include:
include filename
The option -h causes quoted strings to be turned into 27H constructs. -C copies comments to the output, and attempts to format it neatly.
Normally, continuation lines are marked with a & in column 1; the option -6x makes the continuation character x and places it in column 6.
Ratfor is best used with f77(1).
