Does your grep support -f?

If so you could just do something like:
Code:
[user@host2: /tmp] cat 1.txt
aaa bbb ccc eee
[user@host2: /tmp] cat 2.txt
aaa bbbb
cccc
dddd
eeee
ffff
gggg
hhhh cccc
[user@host2: /tmp] grep -f <(tr ' ' '\n' <1.txt) 2.txt
aaa bbbb
cccc
eeee
hhhh cccc

NAME
amoverview - display file systems processed by Amanda over time SYNOPSIS
amoverview [[ -config ] config ] [ [-hostwidth width] ] [ [-diskwidth width] ] [ -verbose ] DESCRIPTION
Amoverview displays a chart showing hosts and file systems processed by Amanda along with the backup level performed each day. See the amanda(8) man page for more details about Amanda. OPTIONS
[-config config] Use configuration config instead of DailySet1. [-hostwidth width] Set host field column width to width characters instead of eight. [-diskwidth width] Set disk field column width to width characters instead of 20. -verbose Amoverview can take a long while on large systems. This option reports intermediate steps while it is working. EXAMPLE
This shows the /home file system on host2 was backed up at level 3 on the 8th, 9th and 10th of December, had a full backup on the 11th, a level 1 on the 12th and a level 2 on the 13th. # amoverview date 12 12 12 12 12 12 host disk 08 09 10 11 12 13 host1 / 0 1 1 1 1 1 host1 /var 0 1 1 1 1 1 host2 / 1 1 1 1 1 0 host2 /home 3 3 3 0 1 2 host2 /opt 1 1 1 1 1 1 host2 /var 1 1 0 1 1 1 SEE ALSO
