1The blobcli tool has several options that are listed by using the -h command 2however the three operating modes are covered in more detail here: 3 4Command Mode 5------------ 6 7This is the default and will just execute one command at a time. It's simple 8but the downside is that if you are going to interact quite a bit with the 9blobstore, the startup time for the application can be cumbersome. 10 11Shell Mode 12---------- 13 14You startup shell mode by using the -S command. At that point you will get 15a "blob>" prompt where you can enter any of the commands, including -h, 16to execute them. You can stil enter just one at a time but the initial 17startup time for the application will not get in the way between commands 18anymore so it is much more usable. 19 20Script (aka test) Mode 21---------------------- 22 23In script mode you just supply one command with a filename when you start 24the cli, for example `blobcli -T test.bs` will feed the tool the file 25called test.bs which contains a series of commands that will all run 26automatically and, like shell mode, will only initialize one time so is 27quick. 28 29The script file format (example) is shown below. Comments are allowed and 30each line should contain one valid command (and its parameters) only. In 31order to operate on blobs via their ID value, use the token $Bn where n 32represents the instance of the blob created in the script. 33 34For example, the line `-s $B0` will operate on the blobid of the first 35blob created in the script (0 index based). `$B2` represents the third 36blob created in the script. 37 38If you start test mode with the additional "ignore" option, any invalid 39script lines will simply be skipped, otherwise the tool will exit if 40it runs into an invalid line (ie './blobcli -T test.bs ignore`). 41 42Sample test/bs file: 43 44~~~{.sh} 45# this is a comment 46-i 47-s bs 48-l bdevs 49-n 1 50-s bs 51-s $B0 52-n 2 53-s $B1 54-m $B0 Makefile 55-d $B0 M.blob 56-f $B1 65 57-d $B1 65.blob 58-s bs 59-x $B0 b0key boval 60-x $B1 b1key b1val 61-r $B0 b0key 62-s $B0 63-s $B1 64-s bs 65~~~ 66
