I am working on AIX, and the command works fine :
Code:
$ cat file
AAAAA Not printed
099   Not printed
101   Printed 1
102   Printed 2
XXX   Printed 3 and last
$ xxxx=100
$ awk -v xxxx=$xxxx ' ($1 ~ "^[0-9][0-9]*$" && $1 > xxxx),0 ' file
101   Printed 1
102   Printed 2
XXX   Printed 3 and last
$

When the pattern in in the form of pattern1,pattern2, action is performed on every record starting whith the record that matches the first pattern pattern1, and continuing throught and including the record that matches the second pattern pattern2.

pattern1 -> ($1 ~ "^[0-9][0-9]*$" && $1 > xxxx)
pattern2 -> 0 Is equivalent To 'End Of File' since 0 is considered as false by awk.



Code:
awk -v enable=0 -v xxxx=$xxxx ' enable != 1 && $1 ~ "^[0-9][0-9]*$" && $1 > xxxx { enable=1} enable ' file

enable != 1 && $1 ~ "^[0-9][0-9]*$" && $1 > xxxx { enable=1}
If a valid record have not been found (enable!=1) and if the current record is valid (tests on field $1), memorize valid record found (enable=1) so from this point all records must be printed.

enable
Test if a valid record have been found (false if enable==0, true otherwise).
The default action is 'print $0'

Jean-Pierre.

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
