Top Forums UNIX for Advanced & Expert Users Alternative to sort -ur +1 required Post 302719575 by Mike Smith on Monday 22nd of October 2012 04:14:02 PM

@Don

Since this works perfectly on a different box and occassionally on this one I was hoping that I'd not have to reinvent this thing to fix my problem.

However I think what you're describing is basic enough for me to manage.

sort -k2 -k1,1 newest-data one-month-data archive-data | sort -ur > output

Sound about right?

And yes if there are two identical lines with just the timestamp being different then I'd like to keep the biggest number (newest)

ar [dmpqrtx][abciluv] [posname] archive [file ...] aal [dpqrtx][clv] archive [file ...] EXAMPLES
ar r libc.a sort.s # Replace sort.s in libc.a ar rb a.s libc.a b.s # Insert b.s before a.s in libc.a DESCRIPTION

The following keys are allowed: d: Delete. Ar will delete the named members. m: Move named files. Ar expects a, b, or i to be specified. p: Print the named files (list them on stdout) q: Quickly append to the end of the archive file. r: Replace (append when not in archive). t: Print the archive's table of contents. x: Extract The keys may optionally concatencated with one or more of the following: a: After posname b: Before posname c: Create (suppresses creation message) i: Before posname l: Local temporary file for work instead of /tmp/ar.$$$$$ u: Replace only if dated later than member in archive v: Verbose SEE ALSO
