Bash Reference Manual > Aliases
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."
Bash Reference Manual > Filename 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."

A trap on ERR, if set, is executed before the shell exits."

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.

sed : using colons as separators instead of forward slashes | commandlinefu.com
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.

"With an ENUM we're actually storing pieces of data in a place that was only intended to hold crucial information about the model" "in large systems the effect of normalization can already tax the limits of human comprehension and complicate queries" "Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered."

User-Defined Types,8.3 Enumerated Types "some people claim, that MySQL ENUMs are much faster than separate tables, especially on large databases. Furthermore, enums can give you some savings in database size, depending on the implementation. For example, a MySQL ENUM occupies only one byte for up to 255 values and two bytes for up to 65535 values."

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?

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.

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.

.SyncIgnore is great but... - BitTorrent Sync - BitTorrent Forums
page's description: .SyncIgnore is great but... - posted in BitTorrent Sync: .SyncIgnore is a file where you can filter out files you don't want synced.  However it seems that when I put files in here bittorrent decides to delete those files rather than leave them un-touched.  That is unexpected.  Is this a bug?  Expected behavior?  Am I using it wrong?

Move synced directory - BitTorrent Sync - BitTorrent Forums
page's description: Move synced directory - posted in BitTorrent Sync: I would like to move where a directory is synced to without re-syncing it. Suppose I have given a read-only key to 10 other people, and now I want it stored in a different place on my machine. Is there any way of doing that without having them all delete the old and add a new key?
