I recently discovered something strange about join on our 4.3 system. If you try to do a join of two files and either one of the files has blank lines (newline characters) at the beginning, the join fails. No output is produced. Join appears to abort when it finds a line containing only a newline. I also tried inserting a blank line in a file after some non-blank lines. In this case, the join worked up to the point of the blank line; then it stopped. I tried doing a join of files that contained blank lines on our SunOS 4.0 system and the join worked fine. My question is, should this be considered a bug? If so, will fixing it cause some other program that depends on join to fail? Any comments are appreciated. Warren Burnett warren@wucs1.wustl.edu
