Anybody know and command to count any characters in file? I would like to know the total number of character " (quote) in file. My idea is to check if in a script the total number of this character is pair.
View 4 RepliesWrite a script that will take a list of filenames as arguments and output a count of how many of them are regular files, and how many of them are scripts (if the file is executable, it will be assumed to be a script file)
Counts always come back as 0
I'm trying to find a script that will return me the largest number of repeating characters. Say, I have the following line in a text file: 12345AAAAA6789AAA
I want it to return 5, because "A" is repeated 5 times in this line (more than 3 at the end).
How do I count the number of occurrence characters in a string in an efficeint way ?
How do I reverse the words in a string with out using temp variables if possible . (if not possible use temp variables ?
Why do I specify dependedcies for header files in the Makefile ?
I want to be able to use Ctrl+R to have reverse-i search. Also if I press Shift+Up Arrow after typing the first few characters of a recently executed command then the shell should complete the command by finding the most recent commmand having the same first few characters.

I'm trying to make and make install a driver for my wireless, every time, though, I use the make command, it'll start at 0 and cound almost up to 200,000 and then the computer freezes. I've tried different drivers, same result. I've tried ndiswrapper but that didn't work either.

Create the file ~/license_counts, which tables the number of occurrences of packages which are licensed under a given license, for the top 5 most commonly used licenses, sorted in numerically descending order. If performed correctly, your file should be formatted similarly to the following. (Do not be concerned if the actual counts or license names are different. Also, you might notice logically similar licenses, such as LGPL/GPL and GPL/LGPL. Do not make any attempt to combine them into a single entry.)
The resulted format:
I tried some method but cannot get it to work.
I need to parse the file of same name which exist on different servers and calculate the count of string existed in both files.Say a file abc.log exist on 2 servers.I want to search for string "test" on both files and calculate the total count of search string's existence.For example if file abc.log on server 1 has string "test" 2 times
and file abc.log on server 2 has string "test" 4 times.then the output will beStringName : Countexampletest : 6 timesNote : I have created the password less connectivity using ssh-keygen.
This has to also show the line count. I can get it to show the files but not the line count. What is the single command used to identify only the matching count of all lines within files under the /etc directory that contain the word „HOST? List only the files with matches and suppress any error messages.
View 4 Replies View RelatedI want to count the digits in between the text in a file.
e.g.
write down the form
2.3 3.3 3.0 505.0 0.777E-07
22.3 3.3 5.0 503.0 1.777E-04
Then read this.
How can i do the counting of these digits present in between a text in a file?

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?

I want to understand what is wrong with my command line. When I can do the some of following in a script but not in a command line. I have been working through the tutorial at [URL]. When I got stuck at the section Working with Multiple Lines. These script works fine.
#!/bin/sh
sed '
# look for a "#" at the end of the line
/#$/ {
# Found one - now read in the next line
N
# delete the "#" and the new line character,
s/#
//
}' file
In my case I am looking for or return ^M.
#!/bin/sh
sed '
# look for a "#" at the end of the line
/
$/ {
# Found one - now read in the next line
N
# delete the "#" and the new line character,
s/
//
}' file
The problem is when I try to convert it to a single line shell command it gives me an errors.
sed '/
$/ {N s/
//}'
sed: -e expression #1, char 10: extra characters after command
sed '/
$/{N s/
//}'
sed: -e expression #1, char 9: extra characters after command
sed '/
$/{Ns/
//}'
sed: -e expression #1, char 8: extra characters after command

I have a utility that works with files. The utility is crashing at after about 120 files. The input to the utility is a file containing a filelist. I want to cut the file with the file names in it to seperate files containing about one hundred or so. My thought was to determine the number of lines/100 and then use head and delete to create temporary files to run the utility multiple times to prevent the crash. When I tried to create a variable using the wc -l command the output gives me the number of total lines but it also includes the filename of the input file. (873 Filename.txt) I can not figure out how to remove the Filename.txt from the variable.

View 3 Replies View RelatedI'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.)
