A comment:
the existence test a[$1] can give different results on different awk versions, and also it adds an empty array element if there was none.
Better is the test ($1 in a).
I think one should recode the whole thing:
This version stores the $1 (field #1) only as an index, not as a value. Therefore, at the END the index is printed before the value.
There are files on a remote server with the file name ending in "mm-dd-yy.txt". The script I am running is:
mls "Daily_Service_Text_File_*" /my/local/dir/Filelisting.txt
nawk -F_ -f file.awk /my/local/dir/Filelisting.txt | sort -k1n | cut -f2- | tail -1
It worked up too "12-31-07.txt" but... (3 Replies)

I have then cut this string so that I only consider the 003 part. I would then like to... (3 Replies)
I'm reading about command substitutions and came across this little function in my book:
function lsd
{
date=$1
ls -l |grep -i "^.\{42\}$date"|cut -c55-
}
it's a little example which is supposed to select files by modification date, given as an argument to the function.

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
