Synchronizing four shell scripts to run one after another in unix
问题 I have 4 shell script to generate a file(let's say param.txt) which is used by another tool(informatica) and as the tool is done with processing, it deletes param.txt. The intent here is all four scripts can get invoked at different time lets say 12:10 am, 12:13 am, 12:16 am, 12:17 am. First script runs at 12:10am and creates param.txt and trigger informatica process which uses param.txt. Informatica process takes another 5-10 minutes to complete and deletes the param.txt. The 2nd script
