We are using Unix commands to run some backend process such as to delete rows in perticular table, to drop and enable the Indexes. We can use PMCMD command to run the workflows by using Unix .
Suppose during one process a file is generated in one path and during the running of the worflow you want it to place in another path, so for this we need to use unix command "cp soure pathname targt pathname".
Generally all informatica jobs are automated, and for this automation we need a tool , in general unix based tools are prefered, like control-m, autosys.. etc. so for the job to run tru tools it must be in the unix script form, so there pmcmd worflow name ... etc will be used/
