I want to search a word suppose "abcd" in all the files(Including hidden and all possible files) in dir suppose /home/john/?
This is what I tried, I am running the below command and its getting stuck for more than 24 hours.
command --> find /home/john -type f -exec grep -iH 'abcd' {} \;
Result something which will show all the files which have this particular word or any file which is have the name as our search word.
Thanks
What about using grep recursion option ?
grep -r abcd /home/john

i recently started learning linux because a ctf contest is coming in the next months. The problem that I struggle with is that i am trying to make a bash script that starts from a directory, checks if the content is a directory or other kind of file. If it is a file,image etc apply strings $f | grep -i 'abcdef', if it is a directory cd to that directory and start over. i have c++ experience and i understand the logic but i can't really make it work.I can't succesfully implement the loop that goes thru all the subdirectories. All help would be appreciated!
you don not need a loop for this implementation. The find command can do what you are looking after.
for instance:
find /home -type f -exec sh -c " strings {} | grep abcd " \;
explain:
/home is you base directory can be anything
-type f: means a regular file
-exec from the man page:
"Execute command; true if 0 status is returned. All
following arguments to find are taken to be arguments to
the command until an argument consisting of ;' is encountered. The string {}' is replaced by the current
file name being processed everywhere it occurs in the
arguments to the command, not just in arguments where it
is alone, as in some versions of find. Both of these
constructions might need to be escaped (with a `') or
quoted to protect them from expansion by the shell. See
the EXAMPLES section for examples of the use of the -exec
option. The specified command is run once for each
matched file. The command is executed in the starting
directory. There are unavoidable security problems
surrounding use of the -exec action; you should use the
-execdir option instead."
If you want to just find the string in a file and you do not HAVE TO first find a directory and then a file and then search, you can just simply find the text with grep.
Go to the the parent directory and execute :
grep -iR "abcd"
Or from any place,
grep -iR "abcd" /var/log/mylogs/
Suggesting a grep command on find filter results:
grep "abcd" $(find . -type f)
I would like to go through all the files in the current directory (or sub-directories) and echoes me back the name of files only if they contain certain words.
More detail:
find -type f -name "*hello *" will give me all file names that have "hello" in their names. But instead of that, I want to search through the files and if that file's content contains "hello" then prints out the name of the file.
Is there a way to approach this?
You can use GNU find and GNU grep as
find /path -type f -exec grep -Hi 'hello' {} +
This is efficient in a way that it doesn't invoke as many grep instances to as many files returned from find. This works in an underlying assumption that find returns a set of files for grep to search on. If you are unsure if the files may not be available, as a fool-proof way, you can use xargs with -r flag, in which case the commands following xargs are executed only if the piped commands return any results
find /path -type f | xargs -r0 grep -Hi 'hello'
i want to use only FIND command in linux and search between specific lines in a file for example find a word "hello" between lines 2 and 4 of a file named test.txt,please help.
By this way you can use grep command but not using find for sure.
grep -w "hello" test.txt
The following example uses find to display all .txt files containing the word "hello":
find -name '*.txt' -exec grep -q hello \{\} \; -a -exec echo \{\} \;
You might be able to modify the grep expression to only match where the targeted word is between certain lines.
If your teacher is asking you not to find files which have this match but is instead asking you to match within a specific known file then they have misinformed you - find is most certainly not the command for that job, making your question unanswerable.
Im trying to look for a word like "numbers" in multiple files not just txt files using terminal. I have tried strings -r /media/E016-5484/* | grep numbers But it still doesn't work !
let say you are looking for 1234 in all files which in name contain file_pattern
grep 1234 ` find . -name "*file_pattern*"`
or
find . -name "*file_pattern*" -exec grep 1234 {} \;
If I am not mistaken, you are looking for
grep numbers -r /media/E016-5484
From the manpage:
-r, --recursive
Read all files under each directory, recursively, following symbolic links only if they are on the command line. This is equivalent to the -d recurse option.
I have a big list of log files in a particular directory , related to my java Application under my Linux Remote Servers .
When i do ls on that particular directory it shows a list of files (nearly 100 files )
Now in that List of files , i need to find out a particular word , please tell me , how can i do this ??
The problem is that I cannot open each and every file and search for that word using /
Please tell me how can i search for a word in the list of files provided .
You can use this command:
grep -rn "string" *
n for showing line number with the filename
r for recursive
grep is made for this.
Use:
grep myword * for a simple word
grep 'my sentence' * for a literal string
grep "I am ${USER}" * when you need variable replacement
You can also use regular expressions.
Add -r for recursive and -n to show the line number of matching lines.
And check man grep.
This is a very frequent task in linux. I use grep -rn '' . all the time to do this. -r for recursive (folder and subfolders) -n so it gives the line numbers, the dot stands for the current directory.
grep -rn '<word or regex>' <location>
do a
man grep
for more options
also you can try the following.
find . -name '*.java' -exec grep "<yourword" /dev/null {} \;
It gets all the files with .java extension and searches 'yourword' in each file, if it presents, it lists the file.
Hope it helps :)
You could club find with exec as follows to get the list of the files as well as the occurrence of the word/string that you are looking for
find . -exec grep "my word" '{}' \; -print
use this command
grep "your word" searchDirectory/*.log
