Various application options for bs2fs file systems are presented in this section.
Example 1: Searching CONSLOG files
The stored CONSLOG files for the month of June 2007 are to be searched for particular contents. This search can be executed very simply using the grep command if the files are available in a bs2fs file system.
This example requires that the bs2fs container must already have been created.
Proceed as follows:
Mount the BS2000 files which are to be processed:
# mount -F bs2fs ':V70a:$sysaudit.sys.conslog.2007-06*' /home/bs2.conslog
Check the result of the mount operation:
# mount | grep 'bs2.conslog' /home/bs2.conslog on :V70A:$SYSAUDIT.SYS.CONSLOG.2007-06* ftyp=text/nosuid on Tue Nov 27 13:52:23 2007
or
# df -k -F bs2fs | grep 'bs2.conslog' :V70A:$SYSAUDIT.SYS.CONSLOG.2007-06* 2000000 331518 1668482 17% /home/bs2.conslog
Display the BS2000 files made available in the bs2fs file system:

Example 2: Converting lowercase notation to uppercase notation
The lowercase notation in a BS2000 file is to be converted to uppercase notation. You can use the tr command for this conversion if the files are contained in a bs2fs file system.
In this example it is assumed that the file to be edited is made available under
/home/bs2.conslog, as in "Example 1: Searching CONSLOG files".
Display the BS2000 files provided in the bs2fs file system:
# ls -l /home/bs2.conslog Total 11836 -r-x------ 1 100 OTHER 151552 Jun 12 12:32 sys.conslog.2007-06-11.007.001 -r-x------ 1 100 OTHER 256000 Jun 13 13:17 sys.conslog.2007-06-12.007.001 -r-x------ 1 100 OTHER 75776 Jun 13 16:26 sys.conslog.2007-06-13.007.001 -r-x------ 1 100 OTHER 73728 Jun 13 17:25 sys.conslog.2007-06-13.007.002 -r-x------ 1 100 OTHER 77824 Jun 14 12:36 sys.conslog.2007-06-13.007.003 -r-x------ 1 100 OTHER 77824 Jun 14 14:42 sys.conslog.2007-06-14.007.001 -r-x------ 1 100 OTHER 5347328 Nov 14 11:12 sys.conslog.2007-06-14.007.002 #
Convert the lowercase notation in the sys.conslog.2007-06-13.007.001 file to uppercase notation:
Write the result to the conslog.out file. (The name of the input file is specified unambiguously in abbreviated form using wildcards.)
# tr '[:lower:]' '[:upper:]' </home/bs2.conslog/*13.007.001 >conslog.out
Check the result by displaying the last records of the input and output files:
