Hi I am using the "script" command in unix to log all the activities performed by users. However, the file generated has a lot of ^M, ^H, ^G characters in it. I would like to know I can suppress these? Or eliminate these using some command. R.Shanthi

One way is to use the tr command to delete the control characters using octal values. Since the octal values of ^M, ^H, ^G are 015, 010, 007 respectively, this command deletes the 3 control characters: tr -d '\015\010\007' < data.file > new.data.file If you need the value of other control characters, but do not have an ASCII chart, use this method to deterine the value: from within vi and in an edit mode, press control-v and then press the control character. Save the file and perform an od -b command on the file. This displays the octal value.
