bash - Get java version in csh (c shell) -


i need java version using c-shell script. i'll need put variable , use afterwards manipulations , tests. in bash command works:

local javaversion=$(java -version 2>&1 | sed 's/java version "\(.*\)\.\(.*\)\..*"/\1\2/; 1q')

but in c-shell, when try:

set javaversion=$(java -version 2>&1 | sed 's/java version "\(.*\)\.\(.*\)\..*"/\1\2/; 1q')

i

"ambiguous output redirect."

error.

yes, have in c-shell, not bash or other language.

i searched , other forums in internet didn't find helpful.

thanks.

here way should works me:

> set javaversion=`java -version |& sed 's/.* version "\(.*\)\.\(.*\)\..*"/\1\2/; 1q'` > echo $javaversion 18

changes are:

  • replace $( command ) `command`; former recommended current posix shell syntax has never been implemented csh.

  • replace 2>&1 | |&; former bourne shell specific, latter csh specific.

  • replace java version .* version; not strictly necessary eased tests java -version returns openjdk version... on machine, not java version...

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
