Hi

Appreciate your try on this.

Assuming the list file contains the list of strings :


Code:
$ cat list
aa
bb
cc


Code:
$ cat file
aa bb       1991      10       15        20
1e ff       1992      10       15        20
cc ff       1990      10       15        20
ee ff       1994      10       15        20


Output:
Code:
$ awk 'NR==FNR{a[$0]=1;next}($1 ~ /^[a-z]+$/ && $2 ~ /^[a-z]+$/ && (!a[$1]) && (!a[$2]) && $3>1990)' list file
ee ff       1994      10       15        20


Is this what you wanted?

Guru.

For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
