any way to squish several date options into one line?
this obviously isnt overly important, but its a bit slow and i was wondering if i could prevent it from re-searching the file several times. i want my matches from the previous and coming three days, as well as today. this is what i have but its weighty and im having trouble finding a way to slim it down.
cd ~/work grep -iT `date --date="3 days ago" "+%b%d"` les grep -iT `date --date="2 days ago" "+%b%d"` les grep -iT `date --date="1 days ago" "+%b%d"` les grep -iT `date "+%b%d"` les grep -iT `date --date="next day" "+%b%d"` les grep -iT `date --date="2 days" "+%b%d"` les grep -iT `date --date="3 days" "+%b%d"` les just need to spit out the lines starting with mmmdd, and im hoping to save some space/time. thanks nomkev |

thats it. its just a function... i skipped the {} to save space.
edit: oops. the file. well it has names, but its basically a txt with: may24 name name may25 name name may26 name name etc... edit again: single digits are in the 'may01' etc Last edited by nomkev; 05-26-2009 at 11:42 AM.. |

I didn't spot that you were ignoring case in your grep commands. Changes in bold red:
Code:
gawk '
BEGIN {
for (i=-3;i<=3;i++)
{
cmd="date --date=\"" i "days\" \"+%b%d\""
cmd | getline
close(cmd)
dy[tolower($0)]++
}
}
{ for (s in dy) if ($0 ~ "^" tolower(s) "[^0-9]") print }' les
