I have a l-column file of more than 10,000 lines with interspersed negative values. What I want to do is add a fixed number (360) everytime a negative value is encountered while leaving the positive ones as is. I need something that will read every line of the file and do the calculation without changing the order of the data. any idea how to implement this using awk? Many thanks in advance.
Hi Friends
How do I do two things from one if statement inside awk? I want to run a script and create a new file from the same condition.
awk '{ if ($2 == ""){print " "|"cd /local/test; ./script.ksh"}{cat > ran_true.txt}}' $IN_FILE
Bolded are the two things I want to be done.

Hi,
I have a data file which contains record count.
So doing wc -l rightfit_balancing_count.dat | awk '{print $1}'] gives me the record count stored in the file.
Now, i want to send a mail from UNIX, if the record count is equal to 0,otherwise it should do nothing.
Any help... (2 Replies)

I cat the file and pipe it to an awk statement like so

I run my script "switch.sh" repeatedly (within 30 seconds). Each time script is triggered, script itself should kill all previous process.
Here is my code:

sudo kill -9 $pid
done

Hi folks,
I have a scenario to convert the update statements into insert statements using shell script (awk, sed...) or in database using regex.

There has to be a way to do this with awk or maybe I'm just focusing on the wrong tool and making this harder than it needs to be.

funtbl - extract a table from Funtools ASCII output
SYNOPSIS
funtable [-c cols] [-h] [-n table] [-p prog] [-s sep] <iname>
DESCRIPTION
[NB: This program has been deprecated in favor of the ASCII text processing support in funtools. You can now perform fundisp on funtools
ASCII output files (specifying the table using bracket notation) to extract tables and columns.]
The funtbl script extracts a specified table (without the header and comments) from a funtools ASCII output file and writes the result to
the standard output. The first non-switch argument is the ASCII input file name (i.e. the saved output from funcnts, fundisp, funhist,
etc.). If no filename is specified, stdin is read. The -n switch specifies which table (starting from 1) to extract. The default is to
extract the first table. The -c switch is a space-delimited list of column numbers to output, e.g. -c "1 3 5" will extract the first
three odd-numbered columns. The default is to extract all columns. The -s switch specifies the separator string to put between columns.
The default is a single space. The -h switch specifies that column names should be added in a header line before the data is output. With-
out the switch, no header is prepended. The -p program switch allows you to specify an awk-like program to run instead of the default
(which is host-specific and is determined at build time). The -T switch will output the data in rdb format (i.e., with a 2-row header of
column names and dashes, and with data columns separated by tabs). The -help switch will print out a message describing program usage.
For example, consider the output from the following funcnts command:
[sh] funcnts -sr snr.ev "ann 512 512 0 9 n=3"

There are four tables in this output. To extract the last one, you can execute:
[sh] funcnts -s snr.ev "ann 512 512 0 9 n=3" | funtbl -n 4
1 147.000 25 147.000 25
2 478.000 84 625.000 109
3 817.000 140 1442.000 249
Note that the output has been re-formatted so that only a single space separates each column, with no extraneous header or comment informa-
tion.
To extract only columns 1,2, and 4 from the last example (but with a header prepended and tabs between columns), you can execute:
[sh] funcnts -s snr.ev "ann 512 512 0 9 n=3" | funtbl -c "1 2 4" -h -n 4 -s " "
#reg counts sumcnts
1 147.000 147.000
2 478.000 625.000
3 817.000 1442.000
Of course, if the output has previously been saved in a file named foo.out, the same result can be obtained by executing:
[sh] funtbl -c "1 2 4" -h -n 4 -s " " foo.out
#reg counts sumcnts
1 147.000 147.000
2 478.000 625.000
3 817.000 1442.000
