awk command question: equivalent to grep.?

rveri — Fri, 25 May 2007 15:43:52 GMT

All,

What is the awk command that is equivalent to "grep -i -e "

Example:
# swlist -l product | grep -i -e "serviceguard" -e "PHSS_34504"

Thanks,

try the one below...

# swlist -l product | awk '$1=="ServiceGuard" || $1=="PHSS_34504"'

Why would you want to use the wrong tool?

The only thing I see in awk is that you can use tolower and then do the compare or regular expression match. To search for multiple patterns (-e), you would have to use ||.

swlist -l product | awk -v IGNORECASE=1 '/serviceguard|PHSS_34504/ { print $0}'

Thanks,

Sandman: command working, you already using the correct string. :)

Ivan,
Looks like in your command IGNORECASE not working: Any way I got the idea.

# swlist -l product | awk -v IGNORECASE=1 '/serviceguard|PHSS_34504/ { print $0}'
PHSS_34504 1.0 Serviceguard A.11.16.00

# swlist -l product | awk -v IGNORECASE=1 '/ServiceGuard|PHSS_34504/ { print $0}'
PHSS_34504 1.0 Serviceguard A.11.16.00
ServiceGuard A.11.16.00 ServiceGuard

Thanks,

HP's awk doesn't support IGNORECASE. But gawk seems to.

Thanks Dennis, Works fine with gawk ( GNU Awk 3.0 ) :

hpap091# swlist -l product | gawk -v IGNORECASE=1 '/serviceguard|PHSS_34504/ { print $0}'
PHSS_34504 1.0 Serviceguard A.11.16.00
SG-Apache-Tool B.02.21 Serviceguard Apache Script Templates
SG-NFS-Tool A.11.23.03 Serviceguard NFS Script Templates
SG-Oracle-Tool B.02.21 Serviceguard Oracle Script Templates
SG-Samba-Tool B.02.21 Serviceguard Samba Script Templates
SG-Tomcat-Tool B.02.21 Serviceguard Tomcat Script Templates
ServiceGuard A.11.16.00 ServiceGuard
hpap091#

Thanks for pointing out that, and it works fine.

imho since you know both product names you don't need to grep or awk for either of them. Instead the command below will suffice for both.

# swlist -l product ServiceGuard -l product PHSS_34504

Hello,

If you are still looking the awk option, here it is:

# swlist -l product | awk ' { tolower($1) } /DigitalVideo|PHKL_8377/'
DigitalVideo B.10.20 Digital Video Software
PHKL_8377 B.10.00.00.AA vmtrace and malloc() patch

The above is from an old machine, I have. For your case it is like:

swlist -l product | awk ' { tolower($1) } /ServiceGuard|PHSS_9397/'

Regards,
Rasheed Tamton.

# swlist -l product | awk '{ tolower($1) } /DigitalVideo|PHKL_8377/'

This doesn't really work. The result of tolower isn't used. The regular expression you have, matches without any need to downshift.

Alright, if you want to use use toupper, you can use:
$ swlist -l product | awk 'toupper($1) ~ /MAKE|GETTEXT/'
This returns:
automake 1.9.6 automake
make 3.80 make
Gettext 0.10.39.4 GNU gettext NLS library
gettext 0.12 gettext

(Your patterns must be the case of your "to*" function.)

swlist -l product|awk ' {if(tolower($1) ~ /(digital|x11|openssh)/) print } '
DigitalVideo B.10.20 Digital Video Software
X11 B.10.20 HP-UX X Window Software
X11BMS B.10.20 HP-UX BMS for X Window Software
openssh 4.3p2 openssh

The only thing to take care is that the regex should be in lower case.

So, in this case need to use /(serviceguard|phss_9397)/
both search strings should be in lower case becuase it is already converted to lower case.
