AWK/SED

opensource4all — Wed, 08 Nov 2006 17:07:32 GMT

Here are certain conditions I need to fulfill

1)Replace a particular filename by the contents of the file in a master file

Tried it with sed but sed cudnt know how to replace the file contents something like
XYZ=srch pattern
ABC=FILE.
XYZ could be anywhere of course :)

sed 's/XYZ/`cat ABC`/g'

Hi,

you where on the right path!
The first change for a solution would be to substitue the singlequotes to double quotes:

1) sed "s/XYZ/`cat ABC`/g"

BUT: you have to keep in mind, that
a character "/" in the file content of 'ABC' will make the substitute pattern invalid because "/" is the pattern delimiter. You can use any character NOT in file ABC for this purpose, e.g.

2) sed "sÂ§XYZÂ§`cat ABC`Â§g"

There is no need for spawning an extra 'cat' process in posix shells, use

3) sed "s/XYZ/$(
Take extra care when ABC contains newlines.

My two cents using ex(1) though I prefer Peter's solution:

# ex -s +"/XYZ/r ABC | /XYZ/d | x" file

Hi:

# perl -pe 'if (s/XYZ//) {chomp;open(FH,"<","XYZ") or die;@a=;print @a}' ABC

Try

export FILE=/path/nameofyourfile

sed "s!XYZ!$(<$FILE)!g"

When using " " quotes you can
embedd variables.

How many points should I assign to replies?
Every response to your question is eligible to earn between 1-10 points. No need to worry about running out of points - when a truly awesome reply rolls in that deserves a 10, you will be able to assign it a 10! However, be careful to assign points based on the value that a reply truly provides. Use the following scale as a guideline:

o N/A: The answer was simply a point of clarification to my original question

o 1-3: The answer didn't really help answer my question, but thanks for your assistance!

o 4- 7: The answer helped with a portion of my question, but I still need some additional help!

o 8-10: The answer has solved my problem completely! Now I'm a happy camper!

Although assigning points is not mandatory, it is a key component of a strong, interactive community, and it is STRONGLY ENCOURAGED. Others have taken time to help you, so please take a moment to give them credit for their assistance!
