General :: Wrapper For Unix Command With Multiple Parameters
Jan 7, 2011I hope to add a wrapper script for the command with different parameters. For example, for any Unix command or script, like below:
command.sh -s p1 -o p2 -q p3
or
command.sh
Probably we could do as this way
cat wrapper
$1 $2 $3 $4 $5 $6 $7 | tee test.log
(assume it has 0 to 6 parameters)
and use it like
wrapper command.sh -s p1 -o p2 -q p3
wrapper command.sh
It is a little ugly to list all fixed parameter as above, do we have better code to handle various parameters?

View 2 Replies View RelatedProgramming :: SORT Command Versus Unix SORT
May 4, 2010We switched from unix to linux and we have an old report that extracted data from a database, output to an ascii file and then sorted the results in the file based on different arguments. The report now blows up when it runs,and I can only guess it is because the options for sort on linux differ slightly from unix.For example, here is one of the commands issued from within the report app that ran on the old unix box:
if sort-sequence = "descending" then
'sort -t~" -f +3.0f -4.0 +5.0r -6.0 -f '
else
'sort -t~" +3.0f -4.0 +1.0f -2.0 -f'
I will eventually rewrite the report to store the data in a local table, but I can simply adjust the options to suit the requirments of linux. Basically, I need to know if this can be a quick fix for the short term.

General :: Seeking Distro With Specific Parameters
Feb 11, 2010This is a WHAT I WANTAND NEED IN A LINUX DISTRO, not a your preference request. Fairly literate with Windows XP, but would like to find a Linux Distro with specific features. Computer used for music (over 14k mp3, ogg Vorbis, etc files) and burning musical learning tracks (I'm a barbershopper) as well as simple surfing and email. Not a gamer. Older Computer: PC with 1.4 GHz Athlon partitioned 320 Gig HD (Windows XP and a Linux Distro??) Only have CD-ROM, cannot download & burn iso DVD's or upload from them. (Can do CD's) Do have a 1 TG Verbatum external HD and a newer computer with a dvd recorder/player
So:
1) MUSTt have a distro that doesn't require a DVD for installation.
2)MUST be able to "update" rather than re-install subsequent releases ( which require backing up files, etc)
3) Like the description of Linux Mint Helena, but it requires installation from a DVD and a re-install..
4) Free distro since I'm learning and trying out different OS's and really resent the increasing cost of Windows OS's as well as the complexity and problems with Windows. I've found that UBUNTU 9.10 doesn't like me. I am very comfortable with LINUX MINT HELENA.
General :: How Increasing RAM Affects Kernel Parameters
Nov 16, 2010We just doubled the RAM on our RHEL 4 production servers...Oracle from 16gb to 32gb and Apache/JBoss from 8 to 32 gb. I am trying to figure out how to get the biggest bang from the increased RAM. Should kernel.shmmax be upped to be 50% of the 32gb....from its current 8gb? I need to create the largest possible SGA and was unable to do so, apparently because the kernel.shmmax value had gone unchanged.
And for the JBoss web servers, also RHEL 4, and particular kernel changes which can take advantage of the increased RAM and provide an immediate performance improvement?
General :: Install Mint 9 KDE With Installation Parameters?

How do I customise the installation of Mint 9 KDE?
