ProgrammingThis forum is for all programming questions.
The question does not have to be directly related to Linux and any language is fair game.

The "-F" tells it to set the field delimiter to "^". Since your pattern has 2 of these between each field you just print every 2nd field. The "," in the print statement tells awk to separate the output with spaces. You can leave out the "," if you want "text1text2text3" instead.
Ugh - you're forcing me to think of proper "sed" syntax:
The following will work:
echo text1^~^text2^~^text3 | sed "s/\^~^/ /g"
This would result in:
text1 text2 text3
For "sed"
The "s" (substitute) the string between the first two "/" with the one between the last two (which is just a space).
The "g" (global) says to do it every time it finds the pattern as otherwise it would only do it the first time.
You need the "\" before the first "^" because in regular expressions "^" has the special meaning of "first character in the line and the "\" escapes this meaning so it sees it as a literal rather than special.
Actually sed is a fairly powerful tool - being lazy I only use it when I need to do so and only think about its syntax then.
