Escape Sequences
Hi Gurus,

Escape sequences \n, \t, \b, \t, \033(1m are not working.

I just practiced these escape sequences. It worked first. Later its not working.

Also the command - echo inside the script editor shows as shaded by a color. Before that echo inside the script editor wont show like this. I don't know what changes happened internally. Please help me on this.


Thanks,
Ganesh

Try:-
Code:
printf "<your escape sequence>"

As you may have an echo command that can't do escape sequences much like /bin/echo
on this OSX machine of mine...
Example:-
Code:
printf "\033[1;34;45m test \033[0m"

OSX 10.7.5, default bash terminal...

EDIT:

Change \x1B to \033 just in case of csh...

Perhaps with your experimentation you have inadvertantly disabled your internal bash
echo command and are relying on the external one which is limited but not insurmountable...

Try:-
Code:
enable echo

From your terminal...
This is the HELP page for it from an OSX 10.7.5, default bash terminal:-
Code:

No manual entry for enable
AMIGA:barrywalker~> help enable
enable: enable [-pnds] [-a] [-f filename] [name ...]
    Enable and disable builtin shell commands.  This allows
    you to use a disk command which has the same name as a shell
    builtin without specifying a full pathname.  If -n is used, the
    NAMEs become disabled; otherwise NAMEs are enabled.  For example,
    to use the `test' found in $PATH instead of the shell builtin
    version, type `enable -n test'.  On systems supporting dynamic
    loading, the -f option may be used to load new builtins from the
    shared object FILENAME.  The -d option will delete a builtin
    previously loaded with -f.  If no non-option names are given, or
    the -p option is supplied, a list of builtins is printed.  The
    -a option means to print every builtin with an indication of whether
    or not it is enabled.  The -s option restricts the output to the POSIX.2
    `special' builtins.  The -n option displays a list of all disabled builtins.
