In fact there is and i am glad to be able to explain - once in a lifetime - "super advanced system admin expert methods" to the audience: You can redirect output streams with the "exec" command:
exec 2>output.stderr
Will redirect every output of every subsequent command to output.stderr.
This way you do not have to worry about truncating the file at all:
Code:
exec 2>output.stderr # truncates the file and redirects stderr to it
job1
job2
job3
exec 2>&- # closes stderr and removes the redirection
I am using the time command in a script however the output of the time command will display on my screen but not my output file. Any Ideas on how to fix this?

recordio
recordio(1) General Commands Manual recordio(1)NAME
recordio - record the input and output of a program
SYNTAX
recordio program [ arg ... ]
DESCRIPTION
recordio runs program with the given arguments. It prints lines to stderr showing the input and output of program.
At the beginning of each line on stderr, recordio inserts the program process ID, along with < for input or > for output. At the end of
each line it inserts a space, a plus sign, or [EOF]; a space indicates that there was a newline in the input or output, and [EOF] indicates
the end of input or output.
recordio prints every packet of input and output immediately. It does not attempt to combine packets into coherent stderr lines. For
example,
recordio sh -c 'cat /dev/fd/8 2>&1' > /dev/null
could produce
5135 > cat: /dev/fd/8: Bad file descriptor
5135 > [EOF]
or
5135 > cat: +
5135 > /dev/fd/8+
5135 > : +
5135 > Bad file descriptor
5135 > [EOF]
recordio uses several lines for long packets to guarantee that each line is printed atomically to stderr.
recordio runs as a child of program. It exits when it sees the end of program's output.
