Top Forums Shell Programming and Scripting How to use grep with multiple patterns? Post 302948784 by cjcox on Thursday 2nd of July 2015 01:22:29 PM

Consider the following... it works. I'm thinking that just like my case below your nidgrps maybe is a string inside a variable?? So you'd use echo instead of cat??


Code:
nidgrps='memberof: example1_samplegroup
memberof: exampleone_samplegroup
memberof: example2_samplegroup
memberof: example3_samplegroup
memberof: examplefake_samplegroup
memberof: example4_samplegroup
memberof: examplefalse_samplegroup'

grouplst="example1|example2|example3|example4|example5|example6|example7"

echo "${nidgrps}" | egrep -i "${grouplst}"

STAPVARS(3stap)                                                                                                                    STAPVARS(3stap)

NAME

       stapvars - systemtap variables

DESCRIPTION

       The  following  sections enumerate the public variables provided by standard tapsets installed, (the installation path is show in the stap-
       paths(7) manual page).  Each variable is described with a type, and its behavior/restrictions.  The syntax is the same as printed with the
       stap option -p2.  Examples:

       example1:long
              Variable "example1" contains an integer.

       example2:string [long]
              Variable "example2" is an array of strings, indexed by integers.

   ARGV
       argc:long
              Contains the value of the  $# value: the number of command line arguments passed to the systemtap script.  It is initialized with an
              implicit begin(-1) probe.

       argv:string [long]
              Contains each command line argument as a string.  argv[1] will equal @1 if there was at least one command line argument.   Arguments
              beyond #32 are not transcribed, and produce a warning message within the begin(-1) probe that initializes this array.

   NULL
       NULL:long
              Simply defined as the number 0.

FILES

       More files and their corresponding paths can be found in the stappaths(7) manual page.
