Unhappy find a word in a file, and change a word beneath it ??
Hi all,

I have a file with lines written somewhat like this.

Code:
aaaa
ccc
aa
linux
browse = no
xssxw
cdcedc
dcsdcd
csdw
police
dwed
dwd
browse = no


cdecec
dsdc
cdc
wd

wdcew
dwed
market
browse = yes

dwdw
wedwe
we
I would like to search word police (which is in middle of file)
and then change the line from browse = no to browse = yes which is after two lines from the word police.

Pls help... I am not so advanced in scripting.

Thanks in advance,
Vikas

Code:
awk '/^police$/ { browse=1; } browse==1 && /^browse/ { print "browse = yes"; browse=0; next; } 1'  <infile >outfile
So search for "police"; when found, change the "state". If in this special state, and the line starts with "browse", print out our special version instead and skip to the next line (skipping the next step). The trailing 1 is the next step which always prints out the current line.
