Given your apparent difficulties following my GNU_EFI ASN.1 X.509 parser code, here is an example of another way to parse X509 .pem files using the OpenSSL development library.

#include <stdio.h>...

A quick Internet search will point you to the source code for many ASN.1 tools. Is there any reason that you cannot use an existing compiler or decompiler whose source code is publicly available?

I am not sure if I understood what you want, since the 2nd post for line "adam,12345" differs from the example in post 1. There are 2 new fields that weren't there in post 1.
Seems there is some...

You can use the popular bits2str function from GAWK manual

function bits2str(bits, data)
{
if (bits == 0)
return "0"

mask = 1
for (; bits != 0; bits = rshift(bits, 1))

I think what you might be looking for is something like this:

sort -t"|" -k1,2 -k3,3r infile

The above will sort pipe delimited file starting with field 1 and ending with field 2 ( -k1,2 )...

I just tried this with GNU sort and awk and it seems to work fine:
sort -r -k5 t3 | awk '!a[$1,$3]++'PS: This record has no space between "Italy" and the pipe character.

Please look at this thread, posted some hours ago:

Have a read of the manual page for find and the section on -mtime

That might have what you need.

when you do ls -lrt *.txt you will not get the total word. So you dont need to use the awk

And consider the case where filenames contain spaces/new-lines.
Also, you don't need a long listing there. A plain ls -rt *.txt is sufficient to get the filenames in the required order.

Sorry should test before I post, this is what you want:
awk -v target="${1:-515|516}" '
$1 == "End" && $2 == "of" {
if( value["Id"] ~ target )
print value["DataField"];

Have a glance at section 5 of the crontab (https://www.unix.com/man-page/OSX/5/crontab/) manual page. It's all explained there.

"cron" runs in the "background", if that's what your other point...

Cron?

I just used 1st_param, 2nd_param, 3rd_param as a quick way to indicate the parameters passed to your script test.sh (it takes the variables file, file1 and file2 from the arguments $1, $2, $3, isn't...

ok,
so you could just use a for cicle to call your script, like:
for sourcefile in `ls /mo/omar/teefa/filesDBM/IBM*.txt` ; do /path/to/test.sh $sourcefile 2nd_param 3rd_param ; done
The shell will...

Hi you can use the date command inside backticks (`) in order to provide a date as filename for the output file, i.e.:
/path/to/test.sh 1st_param 2nd_param `date '+%Y%M%d'`.txt
resulting in the...

Hope this also gives the same output which is easier to understand,

echo "datarecords.txt: male | datarecords.txt: male | datarecords.txt: female" | sed 's/datarecords.txt//g'

grep doesn't do filtering like that, you can pipe it into sed.
$ echo "datarecords.txt: male | datarecords.txt: male | datarecords.txt: female" | sed 's/^[^:]*: /:/;s/|[^:]*: /| :/g'
:male | :male...

That is just to clear the 'value' array as you awk dosn't support delete value. It's splitting the blank string with a seperator of "." and putting the blank result into the 'value' array.

Some slight changes should get it working for you:

nawk -v target=${1:-515} '
$1 == "End" && $2 == "of" {
if( value["Id"] == target )
print value["DataField"];
