Nice - a simple UI like that could be very useful in many situations! Try this: display dialog URL to fetch? default answer set the Url to (text returned of result) -> get file do shell script cd /tmp /usr/local/bin/youtube-dl First download to /tmp, then get title. Could also use the process id (pid) to track progress, etc. command 2>/dev/null /usr/local/bin/youtube-dl -newline Darwin* ) darwin=true ; MINGW* ) msys=true ; esac For Cygwin, ensure paths are in UNIX format before anything is touched. if $cygwin ; then [ -n $ JAVA_ HOME ] do ls=`ls -ld $ PRG ` link=`expr $ls : '.*-> \(.*\)$'` if expr $link :. > /dev/null; then PRG= $link else PRG=`dirname $ PRG ` /$link fi done SAVED= `pwd` cd `dirname \ $ PRG\ `/ > then if [ -x $ JAVA_ HOME/jre/sh/java ] ; then IBM's JDK on AIX uses strange locations for the executables JAVACMD= $ JAVA_ HOME/jre/sh/java else JAVACMD= $ JAVA_ HOME/bin/java fi if [! -x $ JAVACMD ] ; then die ERROR: JAVA_ HOME is set to an invalid directory: $ JAVA_ HOME Please set the JAVA_ HOME variable in your environment to match the location of your Java installation. fi else JAVACMD= java which java >/dev/null 2> Stream Url= Cache fill: 5.00% (16384 bytes) AAC file format detected. = Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders libavcodec version (external) [aac @ 0x7fa1abf39540]element type mismatch 1!= 0 AUDIO: 44100 Hz, 2 ch, floatle, 0.0 kbit/0.00% (ratio: 0->352800) Selected audio codec: [ffaac] afm: ffmpeg ( FFmpeg AAC ( MPEG-2/ MPEG-4 Audio) = AO: [pulse] 44100 Hz 2ch floatle (4 bytes per sample) Video: no video Starting playback. python2 -c 'import urllib2 as u, sys as s, json as j, subprocess as p;p.call([ mplayer, u.urlopen(j.loads(u.urlopen( % +.join(s.argv[1:]).read [ songs ][0][ url ]).geturl.split( )[0] lenny kravitz fly away Detected file format: Audio only Clip info: Title: Fly Away Artist: Lenny Kravitz Album: Baptism Year: Comment: htt Genre: Unknown = Requested audio codec family [mpg123] (afm=mpg123) not available.

This is my sh-file: that I use this to download youtube files in a specific period per day. when I drag the file (y.sh) into the terminal and press return key, it starts to download. but when I use the below command in crontab -e, Nothing happens! /home/deroot/links4dl/y.sh Torify: wrapper for torsocks or tsocks and tor -> man torify youtube-dl: download videos from youtube.com or other video platforms -> man youtube-dl.
My guess is that you could depend on the error code from the google command as well ( I'm assuming it returns error if it failed to upload, but you should probably double check this). for f in.ogv.mov.mp4; do if [!= $ f:2:1 ]; then echo Uploading video file $f if google youtube post -access unlisted -category Tech $f > /dev/null then echo Upload successful. else echo Upload failed. fi fi done A common misconception is that if wants a bracketed expression to evaluate, this is not true, if always takes a command and checks the error status; usually this command is [ which is an alias for test, which evaluates the expression. ( And yes, I'd be surprised if there isn't an optimized shortcut to make it go faster inside bash, but conceptually it's still true). Capturing output is done via backticks, like so result=`command argument a b c` or using $ result=$(command argument a b c) but it's probably better to use the error code in this case. EDIT: You have a funny if thing in your function. I didn't notice at first, but it can be avoided if you enable nullglob shell option (this will make.mov to expand to the empty string, if there are no files). Also, quot; that $f or it'll break if your file names contain spaces shopt -s nullglob for f in.ogv.mov.mp4; do echo Uploading video file $f if google youtube post -access unlisted -category Tech $f > /dev/null then echo Upload successful. else echo Upload failed. fi done HTH.
Digg This - Slashdot This Posted: Technically /dev/null is defined as a null device. Anything written to it is lost forever. If you read the wiki description of /dev/null, you will get to know lots of jargons/metaphors written/referred by UNIX techies a lot. In this article, we will concentrate on the importance of /dev/null, why it is there, and how to use it. Importance When things written to it are lost forever, then why do we need it? This is a valid questions, but we need /dev/null/ to lose information. That's correct, to explain let's take an example: Example 1: Suppose, you want to list all files of directory /var/tmp/ having word foo in its content. To achieve the task, we will write something as: ]$ grep -l foo /var/tmp /var/tmp/storagedata /var/tmp/storagedata.0 grep: /var/tmp/td.log: Permission denied So we got two files having word foo ; but we also an annoying error message which was part of STDERR. We were not interested in any error message, and we wanted to see only those files which I am permitted to read. So, how do I get rid of this error message? Luckily newer version of grep provides a silent option -s, using which we can get rid of this message. But what if I am working on a traditional system, having traditional grep? What if the system command is not having the silent option? The solution is given below: Capturing STDOUT only Using newer grep: ]$ grep -ls foo /var/tmp /var/tmp/storagedata /var/tmp/storagedata.0 Using traditional grep: ]$ grep -l foo /var/tmp 2>/dev/null /var/tmp/storagedata /var/tmp/storagedata.0 In general using any system command : ]$ cmd 2>/dev/null Most of you should have captured the importance of /dev/null by now. In simple words, by using 2>/dev/null, we are asking the shell to redirect the STDERR to /dev/null. This is very useful when we execute system command through a program and expect to get.
