Is there an option, for cat, head, tail, or is there any way, to display a file from last line to first? For example, my file
looks like this:
aaaa
bbbb
cccc
eeee
and I would like to print or display it like this:
eeee
cccc
bbbb
aaaa

Hi, excuse me for my poor english.
My problem is that:
I have a File
i want to add to each line of that file two strings: one at the beginning of the line, one at the ending.
string1="abcd"
string2="efgh"
i want $string1 content $string2 for each line.
Is that possible? (3 Replies)
Hello -
I am running Linux. I want to place a comment char at the beginning of a line in a file. For example:
testvar=`grep username /etc/people
sed -e 's/$testvar/#$testvar/g' /etc/people
I cannot get the above commands to put a comment at the beginning of the line.

How can I specify special meaning characters like ^ or $ inside a regex range. e.g
Suppose I want to search for a string that either starts with '|' character or begins with start-of-line character.
I tried the following but it does not work:
sed 's/\(\)/<do something here>/g' file1

Well here goes:
I tried to write a batch file that adds a specific fixed text to each line of an already existing text file.
for the adding text infront of each line I tried this:
for /F "delims=" %%j in (list.txt) do echo.STARTTEXT\%%j >> list.txt
for adding text after each line I... (0 Replies)
How would you do vim copy line and paste at the beginning, middle, and end of another line. I know yy copies the whole line and p pastes the whole line, but on its own separate line. Sometimes I would like to copy a line to the beginning, middle, or end of another line. I would think this would be... (3 Replies)
I need to comment the lines starting with pattern "exclude" or "exclude=". If the work exclude comes at any other part, ignore it. Also, ignore, excludes, excluded etc. Ie only comment the line starting with exclude.

Hi,
I have a specific requirement to add text at the beginning and end of a plain text file. I tried to use "sed" with '1i' and '$a' flags but these required two separate "sed" commands separated with "|".
I am looking for some command/option to join these two in single command parameter.

FOX(1) General Commands Manual FOX(1)NAME
fox - ab-initio structure determination from diffraction data
SYNOPSIS
fox [options] [file.xml]
DESCRIPTION
The fox (Free Objects for Crystallography) program was made for the ab initio crystal structure solution from diffraction data. Its most
interesting features for ab initio structure determination are:
* versatile description of the crystal contents;
* automatic correction for special positions and shared atoms between polyhedra;
* the ability to use simultaneously multiple powder patterns;
* smart global optimization algorithms;
* a graphical interface with a 3D crystal structure view and live updates during the optimization process.
OPTIONS
This program my be executed with or without command line options or input file (file.xml). It follows the usual GNU command line syntax,
with long options starting with two dashes (`-'). A summary of options is included below. For a complete description, see the fox wiki
http://objcryst.sourceforge.net/Fox/Manual
--help Show summary of options.
--loadfouriergrd map.grd
Load and display 'map.grd' fourier map with (first) crystal structure
--loadfourierdsn6 map.DN6
Load and display a DSN6 fourier map with (first) crystal structure
--nogui
Run without GUI, automatically launches optimization --nogui may be accompanied by the following options:
-n 10000
Run for 10000 trials at most (default: 1000000)
--nbrun 5
Do 5 runs, randomizing before each run (default: 1), use -1 to run indefinitely
-o out.xml
Output in 'out.xml'
--randomize
Randomize initial configuration
--silent
Produce (almost) no text output
--finalcost 0.15
Run optimization until cost < 0.15
--cif2pattern 1.5406 170 5000 .1
Simulate pattern for input crystal, wavelength=1.5406 up to 170o with 500 points anda peak width of 0.1o
EXAMPLES
Fox silicon.xml
Load file 'silicon.xml' and launch GUI.
Fox Cimetidine-powder.xml --nogui --randomize -n 1000000 -o best.xml
Load file 'ktartrate.xml', randomize, then make 1 optimization of 1 million trials, and save the best structure in 'best.xml'.
Fox Cimetidine-powder.xml --nogui --randomize -n 10000000 --nbrun 10 -o best.xml
Load file 'Cimetidine-powder.xml', then make 10 runs (starting from a random structure) of 10 million trials (each run saves one xml
file), and save the best structure in 'best.xml'.
Fox Cimetidine-powder.xml --nogui --silent --randomize -n 10000000 --nbrun 10 --finalcost 200000 -o best.xml
Load file 'Cimetidine-powder.xml', then make 10 silent runs of 10 million trials (each run saves one xml file), and save the best
structure in 'best.xml'. For each run, the optimization stops if the cost goes below 200000.
