I need to write an Unix Shell Script tran.sh that moves the csv input files from
/exp/files folder to
/exp/ready directory. The csv input files are written to
/exp/files folder by an SFTP server whose behavior I cannot trivially change.
In tran.sh shell script I need to ensure before doing a move of that csv input file from /exp/files directory no longer any other process is writing to the file. How can I move it?
