Almost by mistake, I figured out you could do something like:
$ cp foo.data bar1.data
$ ^bar1^bar2
And that runs the same command with bar2.data instead of bar1.data. Now, how about if I have multiple occurrences of the target word? For example:
$ cp foo.data bar.data
$ ^data^index
It only replaces the first data extension. How do I get it to replace both?
Here's the actual line of code, which exists in a bash script:
Code:
I want to replace instances like this:
Code:
with this:
Code:
Using this:
Code:
Which works great when there's only ONE of the pattern on the line. But in a case like the "actual line" I posted first, where there are two patterns, separated by a slash, only ONE gets replaced
Watch:
Code:
Why? There must be (among many other things) something I'm not knowing about sed, that's causing this.
-- I'm currently using the ~ (tilde) as the separator in the sed command. It doesn't matter, I've used / ~ and % with no difference.
-- As a test, I tried putting a different character(s) in the middle of the original pattern instead of the / but that made no difference.
-- I've come up with various similar but slightly different regexs that will do this replacement, but they all have had this same result.
-- I tried the sed single-quoted, double-quoted, and unquoted; the latter fails to execute, and the formers both work as described here: wrong.
Can the Replace function replace more than one word with the same character(s)?
Also, do you know how to access the plugins provided by the gedit-plugins package?
I'm trying to process a postscript file and I want to change alternate pages by finding the string '%%EndPageSetup' (and then adding a line after it).
I've tried using sed with labels and a branching program to ignore the odd occurrences and process the even ones. In the code below I tried searching for the first and ignoring it by jumping to next and processing it and then to the next odd page and so on.
My logic is obviously flawed here as it doesn't work but I've tried the following:
Code:
#!/bin/bash
sed -e '/%%EndPageSetup/{
b even
:odd
/%%EndPageSetup/ b even
:even
s/%%EndPageSetup/%%EndPageSetup++/ b odd}' filename.ps > newfile.ps
Want to search for ~ and delete it as well as to append the entire line to the above line. For Ex:
1111xxxx date Sandy area is ~around this area.3222xxx date There seems to ~left side of map, the colours are accurate (showing green areas)Even if I ~zoom in, the green parks, xxx3258 date The dammed up
~away, the "other" body of water varies ~blackNatural gas leaching.
IT MUST LOOK LIKE:

View 2 Replies View RelatedI wanted to find and replace a string from a perl file. I have written a script in bash which runs the following command.
perl -pi -e "s/$findstring/$replacestring/" testfile
where as $findstring = print F_WC_TMP"$line
";
and $replaceString = $line = join ' ', split ' ', $line; print F_WC_TMP"$line
";
But when I am running the above command, i think it is replacing the $findstring with the above mentioned string and hence it contains a $line, it is looking for the variable $line and not finding the exact string. I am confused about how to search for a string that contains $ in it and replace it with another $string.

View 1 Replies View RelatedI have a text file that contains a single word and I want to write a bash script that will read the word from the text file... The following is my incorrect attempt, as it assigns the name of the textfile to the variable as opposed to the word stored within the textfile:(assume I have a text file value.txt that has its contents a single word, say wordone)
Code:
#!/bin/sh
for f in value.txt
do
echo $f
done
so the output of the above script is value.txt, however I want it to be wordone.to summarise: how do I assign the value of the word contained within a textfile to a variable?

I want to write a small script to rename a bunch of files. Their name is of the form 'long number'|'name'|'extension', for example:
52354Football_part2.flv
2353452Nice_weather_4_ducks.flv
I would like to rename these to:
Football_part2.flv
Nice_weather_4_ducks.flv
If in my script I use something like
Code:
sed s/[0-9]//g
on each file, I will get
Football_part.flv, instead of Football_part2.flv,
and
Nice_weather__ducks.flv, instead of Nice_weather_4_ducks.flv.

Bash's command history is great, especially it is useful when adding the history -a command to the COMMAND_PROMPT.However, I'm wondering if there is a way to log the commands to a file as soon as the Return key is pressed, e.g. before starting the command and not on completion of the command (using the COMMAND_PROMPT option would save the command once the prompt is there again).
I read about auditing programs like snoopy and session recorder like script but I thought they're already too complex for the simple question I have. I guess that deactivating that script logs all the output of the command would lead already in the right direction but isn't there a quicker way to solve that probelm?
