Format file size in Unix in readable format -


when ls -l 

-rw-r--r--   1 jboss    admin  **26644936** sep  1 21:23 mybig.war

how print below

-rw-r--r--   1 jboss    admin  **26,644,936** sep  1 21:23 mybig.war

the proper way format ls output specify block_size.

saying:

block_size="'1" ls -l

would achieve desired result.

quoting above link:

some gnu programs (at least df, du, , ls) display sizes in “blocks”. can adjust block size , method of display make sizes easier read.

a block size specification preceded ‘'’ causes output sizes displayed thousands separators.
