Code:
ls -al | awk '{$6 == "Sep" && $7 < "18"}'

ls -al | awk '{$6 == "Sep" && $7 < "18"}'

I have changed the syntax of the awk command. and i am not sure what exactly tefflox is trying to achive, i had also requested tefflox to specify his requirements so that i could make the appropriate changes to the condition

i am trying to compress all files older than ten days old.. your script, as such:

Quote:
"awkscript" 23 lines, 255 characters
#! /bin/ksh

read x

for file in `ls -lF | awk '{$6 == "Sep" && $7 < "18"}'`

do

mv $file compressed.tar/$file
read x

done

for file in `ls -lF | awk '{$6 != "Sep"}'`

do

mv $file compressed.tar/$file
read x

done

tar -cvf compressed.tar tartar
gives these errors:

Quote:
$ ./awkscript

awk: syntax error near line 1
awk: illegal statement near line 1
awk: syntax error near line 1
awk: illegal statement near line 1
tar: compressed.tar: Is a directory

also, you could try the find command with mtime option and exec to compress the file. right now i dont have access to the unix box, anyways, the command should look something like

Code:
find . -mtime 10 -exec tar -cvf destinationfilename source filename

now i'm learning that my $file variable is wrong, should be something like

for $9 in `ls...." where $9 is the actual file name

it's giving me errors trying to mv the permission lists & stuff

but it means i am making progress, w/ your generous help :-)

Quote:
#! /bin/ksh

read x

for file in `ls -lF | awk '$6 == "Sep" && $7 < 18 && $9 !~ /\//'`

do

mv $file compressed.tar/$file
read x

done

for file in `ls -lF | awk '$6 != "Sep" && $9 !~ /\//'`

do

mv $file compressed.tar/$file
read x

done

tar -cvf compressed.tar compressed

how do I make "file" change to the name of the field $9 in the ls -lF, which is the name of the file?

Quote:
#! /bin/ksh

function file() {

return ( ls -l | awk $9);

}
???
