Top Forums Shell Programming and Scripting Mkbootfs writing to stdout in bash script Post 302795443 by hanson44 on Wednesday 17th of April 2013 06:40:28 PM

You can see what is happening, why it does not work, if you use "set -x" at the top of the shell script.

Unless there is some good reason (can't think of any), do not try putting an entire command line, including redirection, into a variable.

I would suggest the following, to improve readability, to get rid of extremely long line which is maybe causing confusion:
Code:
dir=/root/Desktop/build_cm10/android_cm-10.1/system/out
   cmd=$dir/host/linux-x86/bin/mkbootfs
 input=$dir/target/product/n7100/recovery/root
output=$dir/target/product/n7100/ramdisk-recovery.cpio
$cmd $input > $output

xcursorgen [ -V ] [ --version ] [ -? ] [ --help ] [ -p dir ] [ --prefix dir ] [ config-file [ output-file ] ] DESCRIPTION
Xcursorgen reads the config-file to find the list of cursor images along with their hotspot and nominal size information. Xcursorgen con- verts all of the images to Xcursor format and writes them to the output-file. Each line in the config file is of the form: <size> <xhot> <yhot> <filename> <ms-delay> Multiple images with the same <size> are used to create animated cursors, the <ms-delay> value on each line indicates how long each image should be displayed before switching to the next. <ms-delay> can be elided for static cursors. If config-file is not specified, or is specified as "-", standard input is used for the configuration file. If output-file is not speci- fied, or is specified as "-", standard output is used for the output file. OPTIONS
-V, --version Display the version number and exit. -?, --help Display the usage message and exit. -p dir, --prefix dir Find cursor images in the directory specified by dir. If not specified, the current directory is used. SEE ALSO
