QUESTION1: grep only exact string. QUESTION2: find and replace only exact value with sed
QUESTION1:
How do you grep only an exact string. I am using Solaris10 and do not have any GNU products installed.
Contents of car.txt
CAR1_KEY0
CAR1_KEY1
CAR2_KEY0
CAR2_KEY1
CAR1_KEY10
CURRENT COMMAND LINE: WHERE VARIABLE CAR_NUMBER=1 AND KEY_NUMBER=1
grep ^CAR$CAR_NUMBER"_KEY"$KEY_NUMBER car.txt
OUTPUT:
CAR1_KEY1
CAR1_KEY10
OUTPUT WANTED (HOW DO I ONLY GET THIS):
CAR1_KEY1
QUESTION2:
I have a similar problem with sed (find and replace) using the same input file car.txt.
COMMAND LINE: WHERE VARIABLE CAR_VALUE=1000
sed 's/^CAR'$CAR_NUMBER'_KEY'$KEY_NUMBER'.*/CAR'$CAR_NUMBER'_KEY'$KEY_NUMBER' '$CAR_VALUE'/1' car.txt > new_car.txt
OUTPUT:
CAR1_KEY0
CAR1_KEY1 1000
CAR2_KEY0
CAR2_KEY1
CAR1_KEY1 1000
OUTPUT WANTED (HOW DO I ONLY GET THIS):
CAR1_KEY0
CAR1_KEY1 1000
CAR2_KEY0
CAR2_KEY1
CAR1_KEY10

assetutil
assetutil(1) BSD General Commands Manual assetutil(1)
NAME
assetutil process asset catalog .car files
SYNOPSIS
assetutil [-ViotshMgpT] inputfile
DESCRIPTION
assetutil processes a .car file generated from a image catalog removing requested scale factors, device idioms, subtypes, performance and
memory classes. When thinning scale, idiom, subtype, performance, memory, and graphicsclassfallbacks can be given multiple times, the result-
ing file will contain all of the assets that match all of the parameters given. If scale, idiom, subtype and graphics class are given in one
set, the same parameters must all be present in the subsequent set of parmeters. (IE the count must match)
A list of flags and their descriptions:
-V version information for assetutil
-I Produce a JSON description of the asset catalog object with the given name to --output directory if given or to stdout if no output
path given. If no name is provided, report on the contents of the entire car file.
-i Keep all assets that have idiom that is given on the command line.
-s Keep all assets that have scale factor that is given on the command line, present scale factors will not be removed if there is no
fallback available.
-p Keep all assets that have the display gamut that is given on the command line, present display gamuts will not be removed if there
is no fall back avaliable.
-M Keep all assets that have memory class that is given on the command line, present memory class will not be removed if there is no
fallback available.
-g Keep all assets that have graphics class that is given on the command line. The present graphics class will not be removed if there
is no fallback available.
-h process the hosted idioms list, this is a list of the idioms that must always be preserved in the car file. This list cannot contain
universal, and the different idioms should be given in a comma separated list.
-i Idiom to keep. Can be one of universal/phone/pad.
-t Subtype to keep (integer)
-c Main Assets.car file used to supply the names of the assets to the -I (--info) and the dump options -d (--dump) and -D (--dump-
stack).
-o Output file name, if no output file is given then input file is overwritten.
-T compare thinning attributes 'scale=2:idiom=phone:memory=2:graphicsclass=MTL1,2/scale=2:idiom=phone:memory=1:graphicsclass=MTL2,2'
will print to stdout if the files was thinned with the above thinning attributes, would the same Asset file result in both cases.
