Answer for this sed question ??

hey.. read my post completely.. am not giving any solution.. very confused...

hey.. finally got the answer. it search for pattern with 2 characters(one from "father" and one from "baby").

in ur example, u dont have any pattern like that. but look at my first example. it contains "table". t from "father" a from "baby" or a from "father" b from "baby".

hey guess patterns are taken from both first and second keywords specified in brackets...
in my previous post
ciTe and mAke -->TAble
faTher and bAby-->TAble
faTher and Taxi-->boTTle
faTher and tAxi-->TAble

does it make sense

yup...

one more thing, 2 characters need not be consecutive. one from first string and one from second string. tats it. it can be in any order.


Sorry.. characters need to be consecutive.

Guys I didn't get your point..
So can you explain that using the following example,??
[335786@oracleclient ~]$ cat text
father pink powder
pink box table
colour colour colour
jottle jaby pink
father pink hello
pink pink lingavelu

[335786@oracleclient ~]$ sed '/[father][jottle]/s/pink/blue/g' text
father blue powder
pink box table
colour colour colour
jottle jaby blue
father blue hello
blue blue lingavelu

The Last line especially.....

@christopher
i can't get watever u say....
but guess consecutive things is considered

[335802@oracleclient ~]$ sed '/[cite][owle]/s/pink/blue/g' 2.txt
father pink powder
pink box table...........///DOESN'T REPLACE THOU ciTe and owLe -->TabLe
colour colour colour
blue bottle baby
pink father baby
pink pink pink


[335802@oracleclient ~]$ sed '/[cite][owla]/s/pink/blue/g' 2.txt
father pink powder
blue box table ................ ///here it is replaced ciTe and owlA-->TAble
colour colour colour
blue bottle baby
pink father baby
pink pink pink


@ mahee


father pink powder
pink box table
colour colour colour
jottle jaby pink
father pink hello
pink pink lingavelu.........////here E from fathEr and L from jottLe form a pattern which is matched to EL in lingavELu
so pink is replaced with blue...

i agree with u. characters need to be consecutive.

Is the Formation of Pattern is by respective index of the strings, or all the possible combinations are considered as search patterns???

all combinations are considered as search pattern. only condition is one character from 1st string(it can be any character, irrespective of index position) and the next character should be from 2nd string.

thx

thanks guys..

but is there a way to match multiple patterns without using "sed -e"????

i don think so... tatsy we have '-e' switch... but its my assumption.. not sure...

cat 1.txt
The baby is pink.
baby wears pink dress.
Pink is its fav color.
father gets baby pink dress.
baby father cos he gets pink dress.
father s happy with pink.
hey elr is as good as pink.

sed '/[father][baby]/s/pink/blue/g' 1.txt
The baby is blue.
baby wears blue dress.
Pink is its fav color.
father gets baby blue dress.
baby father cos he gets blue dress.
father s happy with blue.
hey elr is as good as blue.

WHAT ABT THE LAST LINE????
It is replacing the pink with blue???? the pattern 'elr' has no consec alphabets plus both from 'father' only!!
Am confused!!!
