We have a list of cyclones in the world. Now i got to check whether or not the second field is more than 1000 mm. If so, than the line has to have a[*] at the end of the line. For exemple:
Australia:1411:55.55:Mackay Cyclone 1918:1918:Mackay
to
Australia:1411:55.55:Mackay Cyclone 1918:1918:Mackay[*]
I also have to use a substitute. So far i've got this but it fails, 6,$s/([0-9])111:1/.* [*]
I want to sort a number of lines based on their size:
data:
-------
12345678
87654321
1234
[code]....
Should output as:
-----------------
1
2
12
21
[code]....
But i'm gettings this with sort
----------------
1
12
123
1234
[code]....
Can we sort the above "data" text, based on "number of characters" instead of "character order"?
Any time the word The appears at the beginning of a line, I want to move it to the end of the line and capitalize the new first word in the line. For example, The heaven becomes Heaven the. I'm trying to test this out for my Library.

I've written myself a linux program "program" that does something with a regular expression. I want to call the program in the bash shell and pass that regular expression as a command line argument to the program(there are also other command line arguments). A typical regular expression looks like "[abc]_[x|y]".Unfortunately the characters [, ], and | are special characters in bash. Thus, calling "program [abc]_[x|y] anotheragument" doesn't work. Is there a way to pass the expression by using some sort of escape characters or quotation marks etc.?
(Calling program "[abc]_[x|y] anotheragument" isn't working either, because it interprets the two arguments as one.)

While modifying the definition of my PS1, I saw that "[" and "]" markers should be added to help bash to compute the right display lenght. Many exemples on the web do not use them or even mention them.I searched for a solution to add them automatically, like with sed, but I didn't find any example.Are they still needed and is there a recommandation not to use sed to define PS1?

On my terminal only system ( no Xorg or guis ) I have a font rendering issue. In place of some symbols ( eg double-lines and some other miscellaneous line-drawing shapes) are generic diamonds. Attached is a fbgrab ( png format ) of elinks showing the problem. I have now configured elinks to only use single lines drawing characters ( which work fine ) for now as a work around. Here is my /etc/default/console-setup
Code:
# Change to "yes" and setupcon will explain what is being doing
VERBOSE_OUTPUT="no"
# Setup these consoles. Most people do not need to change this.

The numbers in the FONTFACE show the size of the font matrix. For example Lat2-Terminus20x10.psf is a font for codeset Lat2 with size of the font matrix 10x20 (i.e. 10 columns and 20 rows). If the number of columns is 8 then only the number of rows is specified. For example the font matrix of Armenian-Fixed15.psf has size 8x15.
In text video mode or if you use the RadeonFB kernel module only fonts whose font matrix has 8 columns can be used (that is the size should be a simple NUMBER rather than a NUMBERxNUMBER combination). The other fonts can be used only with framebuffer video modes and with the package 'kbd'. The console package 'console-tools' can not be used
with such fonts.
THE TERMINUS FONT:
The aim of the Terminus font is to reduce the eyes-fatigue when one has to read a lot. Currently this font supports only the Latin, the Cyrillic and the Greek scripts (the Lat15, Lat2, Lat7, CyrAsia, CyrKoi, CyrSlav, Greek, Uni2 and Uni3 codesets). The fonts with font face TerminusBold and size 14 or 16 are optimized for 8 pixels width glyph matrix (in most cases this means framebuffer). The fonts with font face TerminusBoldVGA and size 14 or 16 are optimized for 9 pixels width glyph matrix and can not be used with
framebuffer video modes.
The fonts with font face Terminus and size 14 or 16 can be used both with 8 and 9 pixels width glyph matrix. In the regular text video modes the width of the glyph matrix is 9
pixels. If you use the package svgatextmode then the width is 8 or 9 pixels and you probably know it. The Terminus font in this version of console-setup is version 4.26.

I upgraded in Ubuntu from 2.6.28-13 to 2.6.30 and now I get no line-drawing characters in applications like alsamixer; instead they are replaced by 127-bit chars like 'lqqk'. As a coder, I'd really like to understand what happened - what changed (file in /etc?) affecting terminal capabilities, and what does the kernel have to do with it .

What command could I use in terminal to delete all ASCII characters? That is, delete a-z, A-Z, 0-9, and all punctuation? I have a file containing Chinese characters, and I want to remove everything else and leave just the Chinese.
I can use grep to leave only the lines that have Chinese in them, but this still leaves a lot of non-Chinese stuff on those lines. Does anyone know how I could actually remove everything that isn't Chinese?

View 1 Replies View RelatedI am combining data from a couple different input files and creating an output file in a specific format. I notice that if I use the >> operator, information gets appended to a new line in my output file. This is useful, but if I'd like to append onto the CURRENT line, is there an easy way to do this? I've been googling around and see lots of complicated answers, nothing that suggests to me an easy way to do this. For example, if my output file looks like this:
b1a:] cat test
hello my name is
b1a:]
and I'd simply like to append "Bob", how can I do it? If I use
b1a:] echo Bob >> test
b1a:] cat test
b1a:] hello my name is
Bob
b1a:]
So what I would prefer is some command that would create the result:
hello my name is Bob
