.Sh DESCRIPTION
|
|
Interactive non-login shell sessions in
|
|
.Xr sh 1
|
|
execute the commands in the
|
|
.Nm
|
|
script upon startup, using the
|
|
.Pa ENV
|
|
environment variable with path expansion if set, and otherwise searching for the
|
|
user's script at
|
|
.Pa ~/.shrc ,
|
|
any system administrator provided script at
|
|
.Pa /etc/shrc ,
|
|
or any operating system provided script at
|
|
.Pa /etc/default/shrc ,
|
|
whichever exists first.
|
|

|
|

|
|
script is run instead in interactive login shell sessions.

.Xr shrc 5
|
|
.Sh CAVEATS
|
|
.Xr dash
|
|
does not use the
|
|
.Nm
|
|
script, but instead only uses the
|
|
.Ev ENV
|
|
environment variable.
|
|
To invoke the
|
|
.Nm
|
|
script portably across all standard shells upon startup of non-interactive login
|
|
sells, set the
|
|
.Ev ENV
|
|
variable to the user's
|
|
.Nm
|
|
script per the example in
|
|
.Xr profile 5 .
|
|
.Sh BUGS
|
|
.Xr sh 1
|
|
is currently primitive and cannot execute most scripts.
|
|
Beware of sharing the
|
|
.Nm
|
|
script between it and other shells such as
|
|
.Xr dash 1 .
