Special control characters in file
Hi Guys,

We receive some huge files on to Linux server. Source system use FTP mechanism to transfer these files on our server. Occasionally one record is getting corrupted while transfer, some control characters are injecting into the file. How to fix this issue ? please advice ?

Sample Corrupted Record:

Code:
A|06/02/2013|11/03/2013|90|90|90|92|90|99|99|1|90-90-90-92-90-99-99|90-90-90-92-90-99-99-1|FX|US|6|289814345|289814345|SBC AMERITECH|FX|||US|532024303|U108024050|AT&T INC.|FX|US|1||D31887602||FX|US|0||N|N|S|0|||0|0|0||||D|0||152745w]M-LM-^G|599001.74|0|0|FX|FDFR|

Correct Record is as follows:

Code:
A|06/02/2013|11/03/2013|90|90|90|92|90|99|99|1|90-90-90-92-90-99-99|90-90-90-92-90-99-99-1|FX|US|6|289814345|289814345|SBC AMERITECH|FX|||US|532024303|U108024050|AT&T INC.|FX|US|1||D31887602||FX|US|0||N|N|S|0|||0|0|0||||D|0||152745444.00|599001.74|0|0|FX|FDFR|
