Bash Reference Manual¶
- page's description: Bash Reference Manual
- page's description: Bash Reference Manual "Aliases are expanded when a command is read, not when it is executed" "Aliases are expanded when a function definition is read, not when the function is executed, because a function definition is itself a compound command" note that if statements are also "compound commands", which have aliases expanded when their definition is read (i.e. at the beginning of the if statement, for the entire if statement), not when they are executed, and any aliases for function names in them need to be unaliased *before* the if statement containing the function definition. this is necessary even if the if statement is *not* executed, because the expansion of such aliases will cause syntax errors in the parsing of the if statement itself. "If the last character of the alias value is a space or tab character, then the next command word following the alias is also checked for alias expansion."
- page's description: Bash Reference Manual "If GLOBIGNORE is set, each matching filename that also matches one of the patterns in GLOBIGNORE is removed from the list of matches. The filenames . and .. are always ignored when GLOBIGNORE is set and not null."
- page's description: Bash Reference Manual -e: "The shell does not exit if the command that fails is part of the command list immediately following a while or until keyword, part of the test in an if statement, part of any command executed in a && or || list except the command following the final && or ||, any command in a pipeline but the last, or if the command’s return status is being inverted with !.

Process Substitution¶
- "read -a list < <( od -Ad -w24 -t u2 /dev/urandom )" this can be used to pipe the substituted command to a numbered port instead of passing it as an argument
- "a way to take the exit status into account is to use the command substitution in a simple assignment: then the exit status of the assignment is the exit status of the last command substitution in the assignment(s)." the following doesn't work: "Only other solution that came to mind at this moment would be to use read: ls -l ghost_under_bed | read name" "Another case to watch for is explicit subshells: (somecommand). According to the interpretation above, the subshell may return a nonzero status, but since this is not a simple command in the parent shell, the parent shell should continue." this is why errexit doesn't work properly for subshells on Mac

screen
scrollback
- note that viewing scrollback is much more difficult to do in screen than in the surrounding terminal program (which usually has graphical scrollbars). this is because screen provided scrolling before GUIs were available, so it had to rely on terminal rendering and keyboard commands. the ability to reconnect to a running shell (which is what screen is primarily used for nowadays) was actually an extra feature, rather than the primary purpose (providing scrollback), so it is not as well-engineered for that particular purpose as today's GUI users would like. for a better way to support reconnecting, see persistent shells.

- page's description: sed : using colons as separators instead of forward slashes - sed \"s:/old/direcory/:/new/directory/:\" <file> - Having to escape forwardslashes when using sed can be a pain. However, it's possible to instead of using / as the separator to use : . I found this by trying to substitute $PWD into my pattern, like so $ sed \"s/~.*/$PWD/\" file.txt Of course, $PWD will expand to a character string that begins with a / , which will make sed spit out an error such as \"sed: -e expression #1, char 8: unknown option to `s'\". So simply changing it to $ sed \"s:~.*:$PWD:\" file.txt did the trick.

BitTorrent Sync
- SECURITY WARNING: There is an important security hole in the Linux version of BitTorrent Sync: when btsync is run with no arguments, it makes all your files suddenly *world-readable and world-writable*, via a publicly-accessible, unprotected web interface (the WebUI). The WebUI by default allows anyone on the web to create a sync folder to view and edit any files in directories writable by you. To fix this, you apparently *must* use a config file (with the --config option) which is appropriately secured by setting webui > password. If you are currently running btsync without a secured config file, you should run `killall btsync` to turn off the WebUI. You can use `lsof -i` to verify that the WebUI is not running. The security hole has been reported at http://forum.bittorrent.com/topic/18612-security-hole-in-linux-webui-makes-all-your-files-publicly-accessible/ , but it's not clear when/whether they will fix it.

Alternatively, an updatable view can be implemented using INSTEAD OF triggers (see CREATE TRIGGER)."

This is the same as a regular trigger except that the timing of the trigger firing can be adjusted using SET CONSTRAINTS" "A column-specific trigger (one defined using the UPDATE OF column_name syntax) will fire when any of its columns are listed as targets in the UPDATE command's SET list. It is possible for a column's value to change even when the trigger is not fired, because changes made to the row's contents by BEFORE UPDATE triggers are not considered. Conversely, a command such as UPDATE ... SET x = x ... will fire a trigger on column x, even though the column's value did not change." "For UPDATE events, it is possible to specify a list of columns" "It is possible for a column's value to change even when the trigger is not fired, because changes made to the row's contents by BEFORE UPDATE triggers are not considered"

In this way, notification happens automatically when the table is changed, and the application programmer cannot accidentally forget to do it."
- "PostgreSQL does not require constraint names to be unique within a schema (but only per-table)" this is INCORRECT: UNIQUE constraints must be globally unique because their implicit indexes must be globally unique. trying to create an inter-table duplicate UNIQUE constraint gives the error: -- NOTICE: CREATE TABLE / UNIQUE will create implicit index "x" for table "b" ERROR: relation "x" already exists --

PostgreSQL: assigning ROWNUM (row number) to each returned row | EXPLAIN EXTENDED¶
- page's description: How to create fast database queries
- page's description: (5 replies) The following command works fine when pasing it to psql via the -c option: cat event.csv | \ psql -c "COPY (event_id, event_name) FROM STDIN DELIMITER AS ',' NULL AS ''" When executed from a file via -f, it does nothing (no error messages either): event.sql: COPY (event_id, event_name) FROM STDIN DELIMITER AS ',' NULL AS '' cat event.csv | psql -f event.sql What's the problem? Many thanks in advance. -- Best Regards, Tarlika Elisabeth Schmitz

- "It should be noted that as of version 8.4 the issue with Hash indexes being less efficient and slower than b-tree indexes is resolved"
- page's description: About updateable views user ask many times. Is it supported in PostgreSQL? Can we write Complex updateable views? Answer for above is yes. Till 9.0, we have to use RULE for implementing updateable view. Again, RULE Implementation used to be a bit tidious, since user has to write multiple RULES to implement this feature. Following… "Till 9.0, we have to use RULE for implementing updateable view"

Implementation Limits For SQLite¶
- page's description: Redmine "SQLite takes nearly twice as long even though it doesn't have the precip records and is thus less than half the size."
- "The only solution I've found: [in trigger body] insert into test values (New.id, now()); select raise(ignore); " "No, you can't update NEW. What I tend to do is use a VIEW with an INSTEAD OF trigger"

xpath to sql translation¶
- page's description: Are there any tools (java classes, tag libraries) which can translate xpath statements into a SQL query? Given an xpath query which has a predicate that filters node values or "I've never seen an Xpath to SELECT [] FROM [] WHERE clause translation. And it is not easy to do that, because you have to have rules in how you store xml in a relational database. I think that's also the reason there are no tools to do that." " We have found a couple of products on IBM's Alphaworks site. One of them uses the "DB2 XML Extenders" mapping of XML<=>SQL. The other seems to create a default mapping based on SQL metadata. Both of them are limited to Linux & Windows. While we may use these, our main RDB is DB2 for ISeries. So we are still checking.

compiled Jython vs. CPython | Python | Python¶
- page's description: compiled Jython vs. CPython Python Python "the benchmarks comparing Jython+JIT to CPython are mostly in favour of CPython" "An advantage of jython is that it profits from speedups of the JVM's. Since Java is more widespread than CPython, there is in general more interest in speeding up JVM's than in speeding up the CPython byte code interpreter."
