This will only return for a search of html if that exists on its own line separately. Finding files which contain a certain string using find (1) and grep (1).
Linux find file containing string how to#
I find that aliasing the files that I am interested in helps me create easier scripts then always trying to remember how to get all those files. Which filters out the list fd to files that contain the CR pattern. Then you can simply filter the list like this: grep -U -l $'\015' $(fd) grep -r -H ' text string to search ' directory-path.

grep -r ' text string to search ' /directory-path. grep option ' text string to search ' directory-path.

The Linux syntax to find string in files is as follows: grep ' text string to search ' directory-path. type f -regex ".*\.\(inc\|info\|module\|php\|test\|install\|uninstall\)"' grep command syntax for finding a file containing a particular text string. If you have a set of files that you will always be checking you can alias their paths, for example: alias fd='find. To display filename containing the search string: for i in $(find /path/of/target/directory -type f) do if grep -i "the string to look for" "$i" > /dev/null then echo "$i" fi done ĭo if grep -i "web browser" "$i" > /dev/null then echo "$i" \ To search for the string and output just that line with the search string: for i in $(find /path/of/target/directory -type f) do grep -i "the string to look for" "$i" doneĮ.g.: for i in $(find /usr/share/applications -type f) \ How to find all files containing specific text in Linux? -print0 and -null on the other side of the | (pipe) are the crucial ones, passing the filename from the find to the grep embedded in the xargs, allowing for the passing of filenames WITH spaces in the filenames, allowing grep to treat the path and filename as one string, and not break it up on each space.-type f specifies that you are looking for files.-name “ *.*” : for all files ( -name “ *.pas” -o -name “ *.dfm” ) : Only the *.pas OR *.dfm files, OR specified with -o.in the find specifies from the current directory.

type f \( -name "*.pas" -o -name "*.dfm" \) -print0 | xargs -null grep -with-filename -line-number -no-messages -color -ignore-case "searchtext" type f -name "*.*" -print0 | xargs -null grep -with-filename -line-number -no-messages -color -ignore-case "searthtext"Īnd if you have an idea what the file type is you can narrow your search down by specifying file type extensions to search for, in this case. You can use different options of find to improve your file search.Įxpanding the grep a bit to give more information in the output, for example, to get the line number in the file where the text is can be done as follows: find. When I was looking up how to do this, I came across this solution twice: find / -type f -exec grep -H 'text-to-find-here' \ Just to clarify, I’m looking for text within the file, not in the file name. I’m trying to find a way to scan my entire Linux system for all files containing a specific string of text.
