AIX using ed to perform in place editing 1

[SteveR77]

I am battling with an old AIX server and old version of KSH to create a script that will toggle comments in a file
in order to update which server is active.

The issue is the here document and ed command do not execute. The script runs without errors but the subtitution that I expect to happen isn't.

Below is the block of code related to ed and the here document:

ed $F_NAME <<EOF
1,\$s/#10.7.1.239 genesis jde/10.7.1.239 genesis jde/g
1,\$s/10.7.1.234 genesis jde/#10.7.1.239 genesis jde/g
w
EOF


Thank you in advance for your assistance.

You may need to use "ex" instead of "ed" and also notice the escaping of '#' symbol:

ex $F_NAME <<EOF!
1,\$s/\#10.7.1.239 genesis jde/10.7.1.239 genesis jde/g
1,\$s/10.7.1.234 genesis jde/\#10.7.1.234 genesis jde/g
w
q
EOF!

LKBrwnDBA,


Thank you. I escaped the # for the subtitution but it is still not doing the subtitutions. I will attempt the older global replacement reference and if that fails then will see what happens using ex as you have suggested.

The ironic part is in Suse Linux the script I created works without any issues. However, it is good to knock the rust off and battle the old AIX environment.


Thank you again for your assistance with this and make it a great day.

On AIX use "ex" (EEEE - X)instead of "ed"
