Hi,
I'm not very familiar with unix shell. I want to replace the combination of two carriage returns and one newline with one carriage return and one newline. I think the best way to do this is to use sed. I tried something like this:
sed -e "s#\#\#g" file.txt
but it doesn't work.
Thanx... (2 Replies)

I need to replace thousands of carriage returns/line breaks in a large xml file and with spaces. I hope to do so with a script, called, for example, "removeCRs." I would invoke this at the command line as
ml5003$ sed -f /Users/ml5003/removeCRs oldFile > newFile
The script, I presume, would... (4 Replies)
Hello, I have read a few threads on this subject and tried a few things out, but still come up short.
There was one good example, then the last reply was something to the effect of 'Use Sed' & 'Read a book'...
Well I read a bunch of online tutorials on sed, awk, tr, but still can't get the... (2 Replies)
Hello,
I need help adding carriage returns at specific intervals (say 692 characters) to a text file that's one continous string. I'm working in AIX5.3. Any quick help is appreciated.
Thanks! (2 Replies)

set_role
SET ROLE(7) PostgreSQL 9.2.7 Documentation SET ROLE(7)NAME
SET_ROLE - set the current user identifier of the current session
SYNOPSIS
SET [ SESSION | LOCAL ] ROLE role_name
SET [ SESSION | LOCAL ] ROLE NONE
RESET ROLE
DESCRIPTION
This command sets the current user identifier of the current SQL session to be role_name. The role name can be written as either an
identifier or a string literal. After SET ROLE, permissions checking for SQL commands is carried out as though the named role were the one
that had logged in originally.
The specified role_name must be a role that the current session user is a member of. (If the session user is a superuser, any role can be
selected.)
The SESSION and LOCAL modifiers act the same as for the regular SET(7) command.
The NONE and RESET forms reset the current user identifier to be the current session user identifier. These forms can be executed by any
user.
NOTES
Using this command, it is possible to either add privileges or restrict one's privileges. If the session user role has the INHERITS
attribute, then it automatically has all the privileges of every role that it could SET ROLE to; in this case SET ROLE effectively drops
all the privileges assigned directly to the session user and to the other roles it is a member of, leaving only the privileges available to
the named role. On the other hand, if the session user role has the NOINHERITS attribute, SET ROLE drops the privileges assigned directly
to the session user and instead acquires the privileges available to the named role.
In particular, when a superuser chooses to SET ROLE to a non-superuser role, she loses her superuser privileges.
SET ROLE has effects comparable to SET SESSION AUTHORIZATION (SET_SESSION_AUTHORIZATION(7)), but the privilege checks involved are quite
different. Also, SET SESSION AUTHORIZATION determines which roles are allowable for later SET ROLE commands, whereas changing roles with
SET ROLE does not change the set of roles allowed to a later SET ROLE.
SET ROLE does not process session variables as specified by the role's ALTER ROLE (ALTER_ROLE(7)) settings; this only happens during login.
SET ROLE cannot be used within a SECURITY DEFINER function.
EXAMPLES
SELECT SESSION_USER, CURRENT_USER;
session_user | current_user
--------------+--------------
peter | peter
SET ROLE 'paul';
SELECT SESSION_USER, CURRENT_USER;
session_user | current_user
--------------+--------------
peter | paul
COMPATIBILITY
PostgreSQL allows identifier syntax ("rolename"), while the SQL standard requires the role name to be written as a string literal. SQL does
not allow this command during a transaction; PostgreSQL does not make this restriction because there is no reason to. The SESSION and LOCAL
modifiers are a PostgreSQL extension, as is the RESET syntax.
