Need to make a very fast file existence checker. Passing in 20-50K num of files
In the code below ${file} is a file with a listing of +20,000 files. test_speed is the script. I am commenting out the results of <time test_speed try>.
The normal "test -f" is much much too slow when a system... (2 Replies)
I have a script that processes a fair amount of data -- say, 25-50 megs per run. I'd like ideas on speeding it up. The code is actually just a preprocessor -- I'm using another language to do the heavy lifting. But as it happens, the preprocessing takes much more time than the final processing... (3 Replies)

I have some sample code that's supposed to ssh to another machine using Net::SSH::Perl, execute a command, and print
the output of that command. It's very basic, and it works. However, I noticed that upon logging in:
$ssh->login('username','password');
It takes roughly 10-13 seconds to... (2 Replies)

I have "inherited" a OmniOS (illumos based) server.
I noticed rsync is significantly slower in respect to my reference, FreeBSD 12-CURRENT, running on exactly same hardware.
Using same hardware, same command with same source and target disks, OmniOS r151026 gives:

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.
