Please post your AIX-compatible code to determine if a file is more than a year old based on a ftp (ls) directory listing.

I'm up for a challenge
Code:
M=$(date +%m)
Y=$(date +%Y )
ls -ln | awk -vY=$Y -vM=$M 'BEGIN {
  split("Jan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec",mt,",")
  for(i=1;i<13;i++)p[mt[i]]=i;
}
/^[^d]/ && $8>1970 && ($8 < Y - 1 || $8 < Y && p[$6] < M){ print $9 }'

Just a side note: AFAIK the -v<varname> (with no space between -v and <varname>) is a GNU awk extension, other awk implementations (new awk etc) support the other version: -v <varname> (with a space).

Thanks - don't think I've come across this before. Seems having the space might turn out to be more portable.
AIX 5.3 doesn’t have any trouble with the space missing, so it's not exclusively a GNU awk feature.

The usage string certainly shows a space:
Code:
$ awk --version
awk: Not a recognized flag: -
Usage: awk [-u] [-F Character][-v Variable=Value][-f File|Commands][Variable=Value|File ...]
 
$ awk -vPI=3.14159 'BEGIN { print PI }'
3.14159
 
$ csum -h MD5 $(which nawk) $(which awk)
ba598e3a4ccee166aa8efc7ef9a05a2e  /usr/bin/nawk
ba598e3a4ccee166aa8efc7ef9a05a2e  /usr/bin/awk

Also interesting to note that awk and nawk on AIX 5.3 are the same binary

Thanks!
I didn't know that non-GNU awk implementations (in this case AT&T) support -v<varname>.
