Comment: The short story is I want to find a string in a file
and change it.
Here are the details.
I'm looking for a way to change every occurence
of $source to "JavTemp" in a file called
JavTemp2.java. $source is a variable.
This is what I've got:
sed s/$source/JavTemp/g JavTemp2.java >
JavTemp.java The problem, of course, is that sed recognizes
$source as a pattern rather than a variable.
Is there a way to make sed behave the way I want
or is there a better tact? Thanks for any help you can offer.

Reply: (edit)Have you tried escaping the $ with a \ ? sed s/\$source/JavTemp/g JavTemp2.java >
JavTemp.java

Reply: (edit)After reading the post again, i realized that $source is a variable, not a string. If you want to perform variable substitution with sed, then enclose the expresion in double quotes. source="some string"
sed "s/$source/JavTemp/g" JavTemp2.java >
JavTemp.java -jim

Reply: (edit)Actually, I already have it in qoutes.
source="$1"
$source gets it's value from the command line. I've also tried a million different qouting
combinations in the sed expression to no avail. sed "s/$source/JavTemp/g" JavTemp2.java >
JavTemp.java sed 's/"$source"/JavTemp/g' JavTemp2.java >
JavTemp.java sed "s/\$source/JavTemp/g" JavTemp2.java >
JavTemp.java etc... Maybe sed is the wrong command for this type of
thing.
