[PLUG] egrep syntax correction

[Rich Shepard]

   I have an 851 line data file in which certain lines begin with P followed
by 5 digits. I want to count the number of those lines. Despite reading the
grep man page I am missing the correct syntax.

   The expression
 	egrep -cE "^P[[:digit:]]\{5\}" hrwq.dat
returns a count of zero (0). So do variations of options and search strings.

   What have I missed here?

Happy 4th, all,

Rich
