Top Forums Shell Programming and Scripting Wall command with nice text formatting Post 302912979 by bakunin on Wednesday 13th of August 2014 05:12:45 AM

First off, the exact behavior of wall probably depends on the system you are on. I tried with AIX (oslevel -s says "7100-03-02-1412") and it worked once i surrounded the process substitution with double quotes to protect the output against the interpretation of the shell:

Code:
# wall $(cat /tmp/file)

Broadcast message from bakunin@system (pts/0) at 11:11:19 ... 

line1 line2 line3

but

Code:
# wall "$(cat /tmp/file)"

Broadcast message from bakunin@system (pts/0) at 11:12:04 ... 

line1
line2
line3

I hope this helps.
