Compressing and Decompressing Files

bash script:

# # ex - archive extractor
# # usage: ex <file>
ex ()
{
  if [ -f $1 ] ; then
    case $1 in
      *.tar.bz2)   tar xjf $1   ;;
      *.tar.gz)    tar xzf $1   ;;
      *.bz2)       bunzip2 $1   ;;
      *.rar)       unrar x $1     ;;
      *.gz)        gunzip $1    ;;
      *.tar)       tar xf $1    ;;
      *.tbz2)      tar xjf $1   ;;
      *.tgz)       tar xzf $1   ;;
      *.zip)       unzip $1     ;;
      *.Z)         uncompress $1;;
      *.7z)        7z x $1      ;;
      *)           echo "'$1' cannot be extracted via ex()" ;;

  else
    echo "'$1' is not a valid file"

Common compression tools: gzip, bzip2, or zip.

The bzip2 compression tool is recommended because it provides the most compression and is found on most UNIX-like operating systems. The gzip compression tool can also be found on most UNIX-like operating systems. If you need to transfer files between Linux and other operating system such as MS Windows, you should use zip because it is more commonly used on these other operating systems.

Command: xz. It uses the XZ compression algorithm.

• -d, --decompress, --uncompress: Decompress
• Aliases: unxz is equivalent to xz --decompress Notes: Once the target file has been successfully closed, the source file is removed unless --keep was specified.

Example:

xz -d filename
