I looked into this and it seems that echo has this problem a lot. Some versions use escape characters, others do not. Posix.2 chimes in further restricts what echo can do (by default). http://www.opengroup.org/onlinepubs/007904975/utilities/echo.html Posix defines the escape character handling as implementation defined. But, in the same paragraph, defines them as supported on XSI-conformant systems (thus the xpg option flag in bash). In the informative section of the spec, they suggest using printf(1) instead of echo for portable behavior. Printf supports the escape characters in the format and in the arguments strings when using %b in place of %s. -- enjoy scott _______________________________________________ Rpm-list mailing list Rpm-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/rpm-list
