Hello,

currently, I'm using HP-UX machine.
I would like to copy some of the files, which was generated from 1st Apr to 31st Apr from root user.

I tried with below command but it gives me usage of cp command,


cp -p `ls -lrt |egrep -i "Apr ( [1-9]|1[0-9]|2[0-9]|3[0-1] )"|egrep -v "2004 | 2005 | 2006 | 2007 | 2008 | 2009 | 2010 | 2011 | 2012 | 2013 | 2014 | 2015" | grep root | awk '{print $9}'` /tmp/logs/root/

output,
Usage: cp [-f|-i] [-p] [-S] [-A] [-e warn|force|ignore] source_file target_file
cp [-f|-i] [-p] [-S] [-A] [-e warn|force|ignore] source_file ... target_directory
cp [-f|-i] [-p] [-S] -R|-r [-A] [-e warn|force|ignore] source_directory ... target_directory
cp -R[-H | -L | -P] [-f|-i] [-p] [-S] [-A] [-e warn|force|ignore] source_file ... target
cp -r[-H | -L | -P] [-f|-i] [-p] [-S] [-A] [-e warn|force|ignore] source_file ... target

I think I'm doing something wrong with command. I think HP-UX like Linux but its not.(may be I'm wrong.

Let me know if you need more help,

You're VERY wrong. HP/UX is nothing like Linux, at all. If that command works for you on Linux but not HP/UX, then your only solution is to read the man pages on the cp and egrep commands on HP/UX, to figure out what'd different between them. Chances are, you're not using the GNU versions of them, but the HP/UX versions, which have different syntax.
