I have tracker installed, and when I use "tracker-search ..." from terminal, I can find files as expected. In particular, it searches within file contents, not just the titles.
I was hoping to have similar functionality directly from gnome-shell. I've found a number of extensions to do this such as: [URL] .... but none of them work (gnome 3.14, debian Jessie).
How to set up file contents search directly from gnome in Jessie?
As indicated in the subject, I want to search a text. If the text is present I want to replace it. But if the text is not present, I want to insert it after first line and before last line.
Something very handy to do in a Linux shell, is manipulating files and strings - essentially parsing data. Write a utility which will scan in a text file and search and replace strings. We also want to keep track of how many strings we've replaced.
I know that my command would look like this: <utility name> <filename> <stringToSearchFor> <stringToReplaceWith> Code: #!/bin/bash
I want to search a file for a particular pattern and if pattern found replace the line with new text. i am using awk 'match($0,"pattern") != 0 {print $0} ' filename to check if the pattern exists.how do i get the line number of the pattern and delete that line and replace the line with my new text?
I am not especially cli adept so could someone tell me the best way to use the diff command to get the difference between a string of text and the contents of a file instead of between the contents of two files?
I have an SQL dump, file.sql that has many references to a particular domain, d1.com. I would like to run a command that can replace every occurrence of d1.com with d2.com. I've tried looking into sed before but the man pages are quite daunting.
[Syenite] RegionUUID = 8fc56fdd-0afd-4074-9432-0ae8f42b799f Location = 9992,10007 InternalAddress = 0.0.0.0 InternalPort = 9000 AllowAlternatePorts = False ExternalHostName = 71.171.21.9 What I need to do is find out what the IP address is after "ExternalHostName ="
After that I will need to compare that IP to whatismyip and if it's different then replace it but that is easy to do with sed. I just can't figure this simple hurdle out.
I've got a big text file in which I know have probably made some typos (LaTeX). Sometimes I rewrite sentences several times and then end up with double pieces like "the the" or "is is" without noticing it. Most spell checkers that I can use in LaTeX are very basic so they do not notice these grammar errors. Is there a way that I can search for these repetitions by hand using sed or awk or something along these lines? Is there an app for that?
I have large text files with space delimited strings (2-5). The strings can contain "'" or "-". I'd like to replace say the second space with a pipe. What's the best way to go? Using sed I was thinking of this:
on creating a new perl script which replace IP address from the text file. eg. If in a file, we found any word like 11.222.333.44 then it has to be replaced to XX.XXX.333.44
i need to change a binary file, let's say to find and replace username:
find string: "/home/name/bla-bla-bla/ " new string: "/home/anewname/bla-bla-bla/ "
i can do it, for example, in emacs (hexl-mode), but interesting in writing a script instead. it will be much more better for me if i could do it automatically. is there an analog of: sed 's/string1/string2/g' ? P.S. the best way is to recompile the binary files i have, but there are no sources available.
On windows I really only used Notepad++ as my text editor, it had two features that I loved.What I need to accomplish is what I would do with Notepad++ column editor.I could have like 100 lines, and place the cursor at a column, and goto edit>column editor, and I could insert an incrementing number. (I could also pad the incrementing number with 0s, this was GREAT for making batch files among other things.)So each line at that column had a number higher than the previous line.The other feature that I used sometimes was a search/replace with regex patterns.Does anyone know of an editor that has those features for linux? I am mostly after the column editor insert feature but if you know of one with both features that would rock.
I want to be able to check the contents of a text file for a specific string and remove it from the file from the command prompt. I would basically be searching through a number of files and if a specific string is found I would like it removed automatically. pretty much a find and replace, were the replace is nothing. any one got any ideas on how you would do this. I already have the search part sorted just need to be able to remove the string I don't want from the multiple files.
I'm wanting to mod some PHP files across a hierarchy and thought I'd drive it with find + grep + xargs
I built up a command line which I was confident would do the job, but now can't save the results.
First I tried this:
Code: find . -name *.php | xargs grep serialize | cut -d: -f1| sort -u | xargs sed -i s/serialize/serialise/g but that didn't work: Code: sed: illegal option -- i so I thought I'd try using Code:
I'm just starting out with shell-scripting, but having a problem with making new text files with the touch or cat > commands.
What I've been doing is touch testfile1.txt
Also, I've tried cat > testfile1.txt (text)
Console reports "bash: text1.txt: No such file or directory. Consfusingly, it works fine in the home-directory. But if I move the file to where I want it, I can no longer view, edit, etc. it.
I have to delete a certain line of text from the a textfile via ubuntu's shell scripting.I have done research, and it seems that most people advocate the usage of sed /d option. sed makes does not edit the text file. Hence, most options I discovered involved the use of a temporary variable/textfile and then overwriting the old file with the temporary new file. Is there anyway whereby I can bypass the use of temporary storage containers? I hope there is any magical combination of commands to edit the file directly.
How to list the contents of a folder to a text file. I'm trying to list all my music, including all subfolders, etc. to a text file, but I can't remember the command.
How can read the file /var/etc/allInOne.cfg and distribute its contents on multiple cfg files using C language. /var/etc/allInOne.cfg contain the data and the path of each text file.
The source file "/var/etc/allInOne.cfg "look like this: line1 line2 ... line10 filePath:/var/etc/file1.cfg line12 line13 ... line14 filePath:/var/etc/file2.cfg linen .. filePath:/var/etc/filen.cfg the result will be :
The expected result is: /var/etc/file1.cfg will contain line1 to line10 /var/etc/file2.cfg will contain line 12 to line13 /var/etc/filen.cfg will contain linen to linen-1
Just using shell scripting, how can I insert text into the middle of a file name. The file has a predictable pattern, let's say 3 letters and 3 numbers and I want to insert text in the middle of those 2 patterns. Say ABC123 is the file name. As a result, the file name should be ABC.blah.123
I want to write expdp output in a text file using a shell script
If i write like below:
It will write whatever is there in log file to text file
But, sometimes export fails with out start taking export (without generating log file) because of job already exists error. such times, we dont know about that error until we check manually... so i wrote like below:
But still it is not writing anything in to text file using above stmt...
Im trying to read a file in c++ and search for particular character for example if this is a list that I have:
Alice Bob David
[code]....
if the input is D, it should give David, if its B, gives bob. so in this case, meaning it reads the first character of every line. but if possible I want to make this dynamic so the user can specify which character position he is looking for, so in case he is looking for R as character index 3 in all lines, it should give Charlie. but the problem is, it does now recognize , besides, I do not know how to specify the character position in each line.
