I am using atom as editor. I'd like to replace variable names across files. I've replaced jpy_usd by usd_jpy. I want to do that to all occurrences of jpy_usd in my rails project. Could you tell me if you know how to do it?
First you need to find word 'jpy_usd' by using this shortcut
cmd-shift-f
Then you can click replace all after fill the word that you want to replace.
Refer image below
You may refer to here for more details.
I've tried the following way.
type cmd+shift+f, then search all of jpy_usd in my project
move to one file
select one jpy_usd word, then type cmd+d in order to select the others jpy_usd in the same file. Thus edit them simultaneously

I want to read all the files in the xlsx format starting with a string named "csmom". I have used list.files function. But I do not know how to set double pattern. Please see the code. I want to read all the files starting csmom string and they all should be in .xlsx format.
master1<-list.files(path = "C:/Users/Admin/Documents/csmomentum funal",pattern="^csmom")
master2<-list.files(path = "C:/Users/Admin/Documents/csmomentum funal",pattern="^\\.xlsx$")
#jay.sf solution works for creating a regular expression to pull out the condition that you want.
However, generally speaking if you want to cross two lists to find the subset of elements that are contained in both (in your case the files that satisfy both conditions), you can use intersect().
intersect(master1, master2)
Will show you all the files that satisfy pattern 1 and pattern 2.
I would like to get the list of files with a specific extention in a folder. However, these files has space in the name. So for example, imagining I have files named file test1.txt, file test2.txt, file test3.txt, file test4.txt, if I do
list.files(pattern="file test*.txt")
I got
character(0)
NOTA: Apparentely, using simply pattern="file test*" it works fine but I need the extention file as well.
Try:
list.files(pattern="file test.*.txt")
Actually, what this says is:
list.files(pattern="file test(.*).txt")
(which also works). . refers to any character and * refers to the idea that this character should be present 0 or more times (see ?regex).
In your kast example you said that using pattern="file test*" works but you need a way to search for the extension as well.
All you have to do is Change your code to pattern="file test.*.txt". This would make your code search for any filename that matched "file testX.txt" with any one character in place of X.
In solaris- i need to perform a gzgrep of archives. But i need to filter so not searching ALL the archives- maybe just files with '09.30-12' in the name.. then i want to search IN that particular file or files for a particular expression. I have this close.. but it takes WAY too long as its searching unnecessary files first and matching on those.. then moving onto the October archives and finding what i need in them. I need to basically search any files in which filename contains 'x' then look in those files for text 'y' and output to > fileoutput. Perhaps just change the *.gz to just match on a set of files?? i cannot figure out how though. Any help is MUCH appreciated.
Something like this works- but i get way too much output and it takes way too long.
gzgrep 'firstexpression' *.gz > /fileoutput.file
maybe just files with '09.30-12' in the name..
You could say:
gzgrep 'firstexpression' *09.30-12*.gz > fileoutput.file
or
gzgrep pattern_to_search *filename_pattern*.gz > outfile
I have a textpad file that has rows of text. For e.g.
Cat: Meaning - animal. The cat ran up the house
Rat: Meaning- rodent. The rat lives in the borough and feeds on leftovers
Word 3: Description
Word 4: Description
I have many such record in my file. I want to insert a line break at the end of every record for proper presentation. Doing it manually is tedious. Please help if you know an automated process to insert line break.
You can quickly do this by using a feature called "Regular Expressions" to find and add empty lines.
Open up the Find/Replace (Search menu > Replace)
In the "Find what" field, type the following: (^.+$)\n(^.+$)
In the "Replace with" field, type the following: \1\n\n\2
Tick the "Regular expression" checkbox
Click the Replace All button at least twice, but perhaps 3 times, until you get the message Cannot find the Regular Expression
Untick the "Regular expression" checkbox
Close the Replace dialog
Confirm the file is formatted as you are expecting
Save the file.
You can write a simple C# prgram that uses a loop that adds this code after every line :
But first add the namespace using System.Enviorment
Enviorment.NewLine;
If you have any more trouble i'll help with some code to get started
Open up the Find/Replace (Search menu > Replace)
In the "Find what" field, type the following so that the replace occurs at the end of each line: $
In the "Replace with" field, type the following. Note each 'n' represents a <return>. In this instance, I added a return at the end of a SQL statement, the word 'GO' on the next line and another <return>: \n\GO\n
Started with text file containing:
select * from <tablename>
select * from <tablename>
Ended with text file containing:
select * from <tablename
GO
select * from <tablename>
GO
Hope that helps.
from your text it is difficult to understand what you are intending to do. I'll give you some questions. The answers will help others to help you.
Do you really mean textpad as the product from company helios in UK or do you use this word as a general word for a class of tools (like notepad - but there is a general definition AND the tool as part of Windows).
Your file hase line breaks yet. You don't see them, but in the file itself they are present (in Unix systems line feed (hex code 0A) or in the windows world carriage return followed by line feed (hex code 0D 0A)).
Or would you like to publish your text in HTML? So you have to put the necessary tags around each line like paragraph, line break, list item etc.?
I am belatedly setting up Aptana to use four spaces instead of tabs. I've made the necessary changes to the preferences so every new tab inserts four spaces.
All the existing tabs remain, however, and so I get Mixed spaces and tab errors. How can you do a Replace all to fix this? I've tried ^t, <TAB> etc but it just searches for these as normal strings. What are the correct ways to specify a space and a tab?
I've found myself in similar situation and copying whole source code and repasting it helped me out. Just do as follow on your source code Ctrl+A, Ctrl+C, then Del whole code and Ctrl+V it again. You will get only spaces if have set it in options like you mentioned above.
There's an option in the refactor source menu to convert between tabs and space-tabs.
This worked for me: Edit > Find/Replace... (CTRL+F), check Regular Expressions, type \t and type 4 spaces (I use 4 spaces for tab).
