\"Screenshot<\/a>For those of you that read my other post about useful .cshrc functions<\/a>, you know that I like to automate as many processes as possible. If there is something redundant that I do frequently, I will script it or make a function to take care of it.<\/p>\n

In an effort to assist those of you out there that like to automate processes but use bash instead of C-Shell, I have compiled a list of some useful functions to stick in your .bashrc file. Here is a list of the functions that this post will contain:<\/p>\n

    \n
  1. Extract<\/a>: This function will determine the type of archive you are dealing with, and issue the corresponding command to extract it.<\/li>\n
  2. Compress<\/a>: This function will create a .tar.gz archive of whatever files you give.<\/li>\n
  3. Swap<\/a>: This function will swap the names of 2 different files.<\/li>\n
  4. Clock<\/a>: This is just a random function that will display a digital clock in your terminal window and update every second.<\/li>\n
  5. Cpg<\/a>: This function will copy a file to a directory, and also cd<\/code> you to a directory.<\/li>\n
  6. Mvg<\/a>: This function works like Cpg, but moves the file instead of copying it.<\/li>\n
  7. Findit<\/a>: This function will search for a file with the given pattern in the name.<\/li>\n<\/ol>\n

    <\/p>\n

    \n

    Function Extract<\/h2>\n

    <\/a><\/p>\n

    # Handy Extract Program.\r\nfunction extract() {\r\n          if [ -f $1 ] ; then\r\n             case $1 in\r\n              *.tar.bz2)   tar xvjf $1     ;;\r\n             *.tar.gz)    tar xvzf $1     ;;\r\n             *.bz2)       bunzip2 $1      ;;\r\n             *.rar)       unrar x $1      ;;\r\n             *.gz)        gunzip $1       ;;\r\n             *.tar)       tar xvf $1      ;;\r\n             *.tbz2)      tar xvjf $1     ;;\r\n             *.tgz)       tar xvzf $1     ;;\r\n             *.zip)       unzip $1        ;;\r\n             *.Z)         uncompress $1   ;;\r\n             *.7z)        7z x $1         ;;\r\n             *)           echo "'$1' cannot be extracted via extract()" ;;\r\n         esac\r\n     else\r\n         echo "'$1' is not a valid file"\r\n     fi\r\n}<\/pre>\n<\/div>\n

    \nNote<\/strong>:  findit<\/code> function is NOT case-sensitive<\/p>\n
    Feel free to modify any of the functions to your liking.<\/p>\n
