catitself does not write to file, only to stdout. The shell redirect>does the writing.The problem with your statement is that
cattakes list of file names as parameter, socat $variablewill attempt to print the contents of a file whose name is stored in$variablewhich most likely doesn’t exist.To write the contents of the variable to a file, use
echo $variable >t.h
