I've been trying to decipher your awk command but I'm a little stuck - I understand that the "? :" provides a conditional operator that is found in the C programming language - that has the form:
Code:
expr ? action1 : action2
For the expression do one or the other depending whether the expression is matched or not e.g.
Code:
grade = (avg >= 65) ? "Pass" : "Fail"
But the bit I don't understand is the expression:
Code:
x[$1]++||$0=NR==1
I can see that you're loading $1 into an array and incrementing it... but I really don't know what you're using it for and the second part on the other side of the OR clause is even more confusing
I hope you can explain it to me - I'd really appreciate it
Hello,
I need experts help in converting the below tcl function to korn shell function equivalent.
proc lsNetMaskToBits {mask} {
set dw ; # Top N bits set
set dw 0x ; # Make sure it's hexadecimal, else XOR fails.
puts "lsNetMaskToBits dw $dw"
set dw ; # Complement => low 32-N bits... (1 Reply)
I always find BASH easier than ksh. At my home, i have written this bash script. I am finding it hard to write its equivalent in ksh, any suggestions?

igawk
IGAWK(1) Utility Commands IGAWK(1)NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...
igawk [ all gawk options ] [ -- ] program-text file ...
DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk
BEGIN {
while (getopt(ARGC, ARGV, "am:q") != -1)
...
}
EOF
igawk -f test.awk
