C:\progra~1\trayman>trayman -u
This could be a typo...
In DOS, the > character is a re-direction command. It is used to force default output to another destination. A good example is the DOS's SORT command.
SORT <Jumbled.dat >Sorted.dat
The contents of Jumbled.dat is given to SORT. Instead of writing the sorted data to the screen, SORT writes it to the file Sorted.dat. (It could just as easily be sent to a printer (SORT <Jumbled.dat >PRN))
We can see that < re-directs input and > re-directs output.
As given in your post, C:\progra~1\trayman>trayman -u would be interpreted as a command for the program C:\progra~1\trayman to execute and send its output to a file named trayman. The following -u confused the command interpreter, and caused the error message to be printed and the command aborted. Had the command interpreter continued, your system would not have been able to locate an executable file named C:\progra~1\trayman. An different error message would've been printed.
As you observed, things progressed normally when the correct command, C:\progra~1\trayman\trayman -u was given.
Cheers, PW.
P.S. Besides Re-direction characters, <, and >, DOS supports |, or the pipe command. Pipes direct output from one command to become input for another. An example...
TYPE filename.dat | MORE
This takes the output from TYPE, (the contents of filename.dat) and feeds it to MORE. MORE is the DOS command for displaying data one screenfull at a time.

HELP!!!
My husband had his suit shrunk at the cleaners. It went in as a 40 and came back as a 38. It's never happened to him before. Does this happen often? Can anything be done? |
