Need help converting ctlU (^U) to a \12...

I have a file that ends with a ctlU:

Code:
> cat -v test.file 
blah,blah,blah,GEAEA*1*xx0000111xxx^UIEA*xxx0^U


would like to replace the ctlU (^U) with a "\12"...due to printers or something.

I believe I might be able to utilize the tr command, if I could only identify the correct representation for ctlU (^U)?

Code:
tr '\^U' '\12' < test.file > new.file

any assistance would be appreciated...

To get octal value of that character, use:
Code:
od -c test.file

The tr needs a different notation than ^X? Try \octal, \25 in this case.

Code:
> cat test.file | od -c | tail -2
0006600   7   9   0 025  \n
0006605

Code:
> cat test.file | od -b | tail -2
0006600 067 071 060 025 012
0006605



looks like the following did the trick...thanks Smilie

Code:
> tr '\025' '\12' < test.file > new.file

It works for me using keyboart cntl-u in single quotes:

Code:
$ all256|cat -vt
