When invoking bash as an interpreter, it is converting the .bashrc characters before trying to execute the commands inside. This does not occur with bash 4.2.53.

The .bashrc file is also translated to a different character encoding after starting the latest version of bash. However, if I start bash 4.3 without an empty, or nonexistent .bashrc file then bash starts correctly:

This is my .profile with the exports from the install README.ZOS document:

export _CEE_RUNOPTS="FILETAG(AUTOCVT,AUTOTAG) POSIX(ON)"
export _BPXK_AUTOCVT=ON
export _TAG_REDIR_ERR=txt
export _TAG_REDIR_IN=txt
export _TAG_REDIR_OUT=txt

I’ve searched through the forums and saw a reference to this in a git+bash forum, but it hasn’t been answered, and I feel this problem warrants its own thread. Is there currently any way to circumvent this problem?

Hmmm. I’ve done some testing, but since there are so many interacting pieces (login vs. non-login shells, interactive vs. non-interactive shells, presence or absence of /etc/profile, various dot files, etc…), it’s hard to be sure what’s going on.

That said - it SEEMS to be the case that if I:

• encode my .bashrc as EBCDIC
• tag .bashrc as EBCDIC (using chtag -tc 1047.bashrc)

then it works.

Can you give that a try?

This fixed it! Thanks!
