I was working on a php project which involved in uploading a tab delimited file and then processing it with php on a unix webserver to insert data into a database. The file was produced on a windows machine and so it had windows line endings. I used this trick to strip off the carriage [...]  Ever tried to copy or move a bunch of files on unix/linux from one location to another and see this error message spit out back at you?? $ cp /var/www/* /var/tmp UNIX find to the rescue… $ find /var/www -type f -name ‘*’ -exec cp {} /var/tmp/. \; problem solved! I did not realize how easy it is to join mpeg files with just the windows copy command or unix cat command. On windows the trick is to copy the files while preserving the binary format. Here is how you would do it - copy files1.mpg /b + files2.mpg /b joinedfile.mpg You could also do the following [...] I constantly connect to linux or unix machines using ssh and it can get a little bothersome typing out the IP address repeatedly. Here is the typical syntax to connect to a linux box (random IP address) ssh username@111.11.11.1 Now imagine typing this again and again. Thats where the ssh config file comes to the rescue. You [...] I have a Canon H100 video camera. This records high definition 1080p videos in a digital video format called AVCHD. It has been a pain to watch these videos. First of all, these videos don’t even play properly on my single core PC. My 3-4 year old PC is just not powerful enough.

Cover flow showed up the same album art for each of the songs. I hated this!! The fix is pretty quick. You have to make sure of the following to make your [...] Update: See the comments to see how to do this correctly. the UNIX grep command is very powerful, but the egrep command is even more powerful. You can grep for multiple strings in a file using the egrep command. All you have to do is use the | (or) symbol and add as many strings you [...] I currently have hosting through bluehost.com. I was surprised to see all blog notification emails were coming from username@boxXXX.bluehost.com instead of the email address defined during setup. After a lot of searching online and trying out different things, I think this bug is due to a combination of my hosting company bluehost and wordpress. I [...] I knew there was a way to ftp multiple files without being prompted.It was just a matter of knowing the syntax. It is possible to download several files at once, using the mget command. This command can take several filenames as arguments, and you can even use wildcards to download matching files. For example, the command mget [...] So many times I have wanted to see why my windows is booting so slowly. What drivers are causing problems… Well msconfig has a nice feature to disable the eye candy bootup and just show what drivers are being loaded!! |
