Cisco Support Tools 1.0 User Guide How to Use the CAT Utility 211
-t: show tabs as ^I (only valid if -v given).
-e: show new-lines as $ (only valid if -v given).
-x: expand tabs into the number of spaces specified by the TABS environment
variable or into 8 spaces if TABS is undefined.
-n: no output - don't actually do any output, just do input. Equivalent to '> nul',
except that on some platforms, the latter can be very slow (much slower than
writing to an actual file.) This option is handy for seeing how long it takes to just
read a set of files under varying operating conditions.
-?: Display program description.
Note: If the environment variable CAT exists, its value is used to establish default
options.
Note: You can override an option that was specified in the environment variable by
following the option with a minus '-' sign. For example, to turn off the -v option,
specify -v-.
Note: If the environment variable TABS exists, its value will determine the
number of spaces used to expand tabs. Otherwise, tabs are expanded to 8
spaces.
