Linux Tips

You can make one autostartup script for ubuntu(debian) easily, and put commands to be started up automatically at boot. Here’s what you have to do: sudo nano /etc/init.d/ local.startup You can name the new file whatever you want, but in this example i haveused local.startup . Type #!/bin/sh on the first line of the file. Now type your command(s) underneath, one after the other. Now save and close and make the file executable with sudo chmod +x /etc/init.d/local.startup Make the file to be recognized as an init script: sudo update-rc.d local.startup defaults 80 Now when you restart you will have the commands in the file auto started.

Often I'm asked how to traverse a list of items in a file. You can easily go through a list of items using a for loop. Here's an example of copying selected contents of originalDir to destinationDir via the command line. #sh #for i in `cat   /home/esofthub/mylist.dat ` #do #cp -pr / originalDir /$i / destinationDir /. #echo $i done #done sh – shell cat – lists each item in the list one iteration at a time cp – the copy utility for a local workstation (plain files and directories, no symbolic links) -pr – these options preserve the permission, "p" and copies recursively, "r" echo – lists the item copied
