Full Discussion: Shell input to remove every second file in a directory
Top Forums UNIX for Dummies Questions & Answers Shell input to remove every second file in a directory Post 302672141 by alpha_mouse on Monday 16th of July 2012 04:11:45 AM
Old 07-16-2012
If I wanted to run the script so many times that I just would have ended up with 0001 yes I would have just RM * except the first one yes. But That is obvious not the reason why I am posting this. I need to scale down a batch of photos for a specific reason. Deleting every other file will help me with this process.

I am stuck on how to filter out every other file, to eventually delete it.

awk ‘NR%2 != 0′

should result in every second file right?

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.

Version 1.23.1							  Sun Jan 8 2012						      set_color(1)
