Hello All!
As a beginner user i want to add up sequential values in a text file and want to print total sum as output.The Text file will have values like the following:
class1{root}>less SUM.txt
1140.00 1155.00 1183.00 ... # it continues #
i tried to write a script with for-do looping and awk inside the loop but it didnt work (not a surprise to me ) And i dont know how to end up the looping as it should detect the last value in file (for ex: if there is 5 values it should stop when AWK detects that 6th value is zero). Could you help me please..
Code:
for (( i=1; i<=100; i++ )) do
cat SUM.txt | awk '{total += $i} END {printf "%15.2f\n",total}'
if [ "$awk'{printf "%15.2f\n",total}" -eq 0 ]
then break ## or end up the loop and print the result ##
fi
done

The below awk in bold will look for the ids in file1 in $2 of file2 and if they match print the line in file2. If an id is missing or not found in file2 (like BMPR2 in line4 of file1) I can not figure out how to add it to them to the lines in the output as missing in $3 following the same format....

The awk below produces an output with the original header and only the matching lines (which is good), but the output where the original line numbering in the match found on is used. I can not figure out how to sequentially number the output instead of using the original.
I did try to add... (2 Replies)

break
break(3tcl) Tcl Built-In Commands break(3tcl)__________________________________________________________________________________________________________________________________________________NAME
break - Abort looping command
SYNOPSIS
break
_________________________________________________________________DESCRIPTION
This command is typically invoked inside the body of a looping command such as for or foreach or while. It returns a TCL_BREAK code, which
causes a break exception to occur. The exception causes the current script to be aborted out to the innermost containing loop command,
which then aborts its execution and returns normally. Break exceptions are also handled in a few other situations, such as the catch com-
mand, Tk event bindings, and the outermost scripts of procedure bodies.
EXAMPLE
Print a line for each of the integers from 0 to 5:
for {set x 0} {$x<10} {incr x} {
if {$x > 5} {
break
}
puts "x is $x"
}
