It'd probably be better to not proliferate clutter that way.

How efficient the awk/grep method works depends on how large the files are, and how you're using them.

If different processes write to one file at a time, then there is a risk of file corruption (but not filesystem corruption). The corruption is usually that one of the concurrent writes is simply...

You have been given two suggestions using set -C or set -o noclobber that have nothing to do with mkdir. Have you looked at them?

I don't see how this has anything to do with the topic of this...

I found it. It's a bash-only feature, mind.

set -o noclobber

if ! exec 5>filename
then
echo "Someone else already has filename" >&2
exit 1

There's an instant between 'check' and 'create file' when something else could create that file without bash knowing.

You could use mkdir. That's atomic. The first time it gets called it...

It looks like it should work just fine (although it creates an unneeded process every time through the loop) if you want to completely ignore some command input read from your input file, never run...

Was me, and i removed it because you already answered it but i had overseen.
Though, its not clear to me how it would identify which process to kill, as the file is just touched and you spawned...

Hi gmark99...

<Cough> It would be wiser to make your my_job have an error code in real time, detect it in the main script yet still log it as before...

If you don't understand what's wrong, you also don't know what's relevant.

If you think the program is too big/complicated to post, whittle it down into a smaller, still-complete program which...

So, from this code it seems that your intention is to simultaneously run an infinite number of jobs for every line in some file on your system. You do not care if any of these jobs start...

There are thousands of things that could cause this. SHOW US YOUR CODE!

HI Corona, Thanks for the reply.
Please find the below sample actual xml, in this below example i need to create 4 seperate xmls and update in a .xml file. I will get xml file with only in any of...

I can make code that will work for that exact file but will probably fail for your real application. So it'd be better off to see the actual data you want split in the first place, with confidential...

HI All,
I have to split a xml file into multiple xml files and append it in another .xml file. for example below is a sample xml and using shell script i have to split it into three xml files...

awk -F'(>|<)' '/value1/,/value2/ {if($2=="value1") v1=$3; else a[v1," ",$3]++}END{for (i in a) print i}' inputXML

For above input, output is:

xyx 123
568 zzzzz

I have an xml file with the structure:

<tag1>
<value1>xyx</value1>
<value2>123</value2>
</tag1>
<tag1>
<value1>568</value1>

Hi Pravin
we are not able to generate our real time Order xml...

Its working fine at my end.

try this,

awk '/Order Number=\"/ {a=$0;i=0;while(i<4){getline;a=a"\n"$0;i++};print a > ++j".xml"}' input.xml
