convert binary file into text file

im looking for anothr way to convert binary file into text file
im using old solaris version (exatcly like xxd -r)
thanks

Binary file into text file? Is this an ASCII formatted file and you want to convert the end-of-line characters? Or is it a binary from which you are trying to extract strings?

For the former, search UNIX.com for "end of line" or "EOL" or "convert MAC to UNIX" or something.

For the latter, using the strings program.

Please clarify.
Linux "xxd -r" actually converts hexadecimal to binary.

Assuming you want to convert binary to hexadecimal on Solaris try looking up:
man xd
man od
