I have have 6 empty directory below. I would like write bash scipt if any files less "1000000000" bytes then move to "/export/home/mytmp/final" folder first and any files greater than "1000000000" bytes then move to final1, final2, final3, final4, final4, final5 and that depend see how many files, but I only want ONE file go into 1 directory. I run the command below with great than "1000000000" bytes and see 3 files then that 3 files should go 3 folders (final1, final2 and final3) only. If see more that 6 or 8 files greater than "1000000000" bytes then should go last folder "final5" . Is some kinda script loop through or command to do this? Please help with this task. Thanks

Without writing a script for you, I will offer some thoughts on how I would go about this.

First, it is considered poor practice to parse the output from the 'ls' command in scripts. http://mywiki.wooledge.org/ParsingLs

For getting a list of files to process, use the 'find' command with the '-size' option.

Code:

# Pseudocode to show a general logic

# Find files <1G in size
find . -size -1G -type f

# Find files >1G in size
find . -size +1G -type f
test number of files found
if count=1 then
elif count=2 then
...
elif count>6 then
fi
