Each call to system() creates a separate shell execution environment. Once the commands given to a call to system() complete, that environment is gone.
the first call will not affect the directory in which the second call is run. But, if you perform the cd and the ls and sort pipeline in the same call to system() as in:
Code:
system("cd some_directory
ls -al | sort -k5n");
or
system("cd some_directory; ls -al | sort -k5n");
then the cd command will affect the directory where the pipeline executes.
Do you want the primary sort key of your output to be the file size and the secondary sort key to be the file type? Would you prefer to sort the output with the primary sort key being the file size and the secondary sort key being the file name? Have you looked at all of the options that the ls utility accepts on your system? Do you need both ls and sort? Is there an option to ls that will sort the output by file size and file name instead of having the primary sort key be the file name? If that output is backwards, is there an option to reverse the order of the output produced by ls?
I need to determine if any three files have the same file size in a specified directly?
I have got as far as listing the file sizes but where to go from here?
ls -al |sort -n -r +4 | awq '{print $5}'

Hi guys,
Probably an easy one, but how do you sort a directory so that the files come first, then subdirectories?

subdir 1
file 2
i need it to become
file 1
file 2
subdir 1
as i'm using it in a script to pass each one through a for loop, and would... (2 Replies)

oggz-sort
oggz-sort(1) General Commands Manual oggz-sort(1)NAME
oggz-sort -- Sort the pages of an Ogg file in order of presentation time.
SYNOPSIS
oggz-sort [-o filename | --output filename ] filename
oggz-sort [-h | --help ] [-v | --version ]
Description
oggz-sort sorts an Ogg file, interleaving pages in order of presentation time. It correctly interprets the granulepos timestamps of Ogg
CELT, CMML, Dirac, FLAC, Kate, PCM, Speex, Theora and Vorbis bitstreams. Run oggz-known-codecs(1) for a full list of codecs known by the
installed version of oggz.
Some encoders produce files with incorrect page ordering; for example, some audio and video pages may occur out of order. Although these
files are usually playable, it can be difficult to accurately seek or scrub on them, increasing the likelihood of glitches during playback.
Players may also need to use more memory in order to buffer the audio and video data for synchronized playback, which can be a problem when
the files are viewed on low-memory devices.
Some older Ogg encoders also produce pages which incorrectly have granulepos timestamps recorded that shouldn't be: pages which have no
completed packets must have a granulepos of -1. oggz-sort will correct such granulepos during the process of sorting.
The tool oggz-validate can be used to check the relative ordering of packets in a file, and also to detect incorrect granulepos on pages
with no completed packets. If either of these errors are reported, or use oggz-sort to fix the problem.
Options
oggz-sort accepts the following options:
Miscellaneous options
-o filename, --output filename
Write output to the specified filename instead of printing it to standard output.
-h, --help
Display usage information and exit.
-v, --version
Output version information and exit.
EXAMPLES
Correct the page ordering in broken.ogv:
oggz sort -o fixed.ogv broken.ogv
