You can do   du -h your directory   which will give you the size of your target directory   If you want a brief output  du -hcs your directory is nice

if you just want to see the aggregate size of the folder and probably in MB or GB format  please try the below script   du -s --block-size M  path to your directory

To check the size of all of the directories within a directory  you can use    du -h --max-depth 1

If it helps  You can also create an alias in your  bashrc or  bash profile   function dsize         dir   pwd      if     1           then             dir  1     fi     echo   du -hs  dir      This prints the size of the current directory or the directory you have passed as an argument

Use a summary  -s  and bytes  -b    You can cut the first field of the summary with cut   Putting it all together   CHECK   du -sb  data sflow log   cut -f1

if you just want to see the folder size and not the sub-folders  you can use   du -hs  path to directory   Update   You should know that du shows the used disk space  and not the file size   You can use --apparent-size if u want to see sum of actual file sizes   --apparent-size       print  apparent  sizes   rather  than  disk  usage  although the apparent size is usually smaller  it may be larger due to holes in   sparse         files  internal fragmentation  indirect blocks  and the like   And of course theres no need for -h  Human readable  option inside a script   Instead You can use -b for easier comparison inside script    But You should Note that -b applies --apparent-size by itself  And it might not be what you need   -b  --bytes       equivalent to  --apparent-size --block-size 1    so I think  you should use --block-size or -B     bin bash SIZE   du -B 1  path to directory   cut -f 1 -d              2GB   2147483648 bytes   10GB   10737418240 bytes if     SIZE -gt 2147483648  amp  amp   SIZE -lt 10737418240     then     echo  Condition returned True  fi
