wsadmin.sh reading multiline commands from stdin

Piped wsadmin can't run scripts with flow control, because in that mode a newline separates commands.

Simple example from http://www-01.ibm.com/support/knowledgecenter/SSEQTP_7.0.0/com.ibm.websphere.base.iseries.doc/info/iseries/ae/cxml_jacl.html?lang=en :

set numbers {1 3 5 7 11 13}
foreach num $numbers {
    puts $num
}

output:

[wasuser@oktest-prod-app-2 ~]$ ${WC_WSADMIN:?} -f test.jacl
WASX7209I: Connected to process "dmgr" on node EmProdDmgrNode using SOAP connector;  The type of process is: DeploymentManager

My script is generated. Beside storing it in a temporary file is there a workaround? I know it's possible to do this:

foreach num $numbers { puts $num }

but what if there must be more than one command in the block?

Solution

  • Use a semicolon:

    foreach num $numbers { puts $num; puts $num }

    But you're probably better off writing the script to a temporary file.
