OR # find /tmp/ ! -name "*linux*" ! -name "*lvm*" -type f | xargs grep -w testįind xargs with NOT operator to exclude files-2Īgain similar to find with exec, we can use find with xargs combined with prune to exclude certain files. Now we will adapt this syntax into our example to grep recursively with find command: # find /tmp/ ! -name "*linux*" ! -name "*lvm*" -type f -print0 | xargs -0 grep -w testįind xargs with NOT operator to exclude files-1 The general syntax here would be: find PATH -type f ! -name ! -name | xargs grep Īlternate Method: find PATH -type f ! -name ! -name -print0 xargs -0 grep Now similar to find with exec, we can also use the same NOT( !) operator with xargs. So below example would cover our scenario.ĪLSO READ: Step-by-Step Tutorial: Guide to install systemtap in Linux Method 3: using find with xargs (NOT operator) Syntax to use with single filename: find PATH -type f -name -exec grep + In this example we will use find with exec to search for specific files and grep for our string. Now we can have a file such as nf, nf, nfig so all such files would be eligible when we use " lvm" and " linux" as our regex for filename: In the below examples we will " Search for test string in file that contains " lvm" and " linux" in the filename". For example, I wish to grep for " test" string but only in files which contain " lvm" or " linux" in the filename. We can also define filename in plain text format or regex which should be searched to grep the provided pattern. Grep for a string only in pre-defined files With grep utility we have two arguments which can help you perform grep recursively, from the man page of grepĪnd grep for your string # grep -rw test. How do I grep for a pattern inside all directories and sub-directories of my Linux server? Is it possible to perform grep recursively? Can you show me some examples to grep for a pattern or a string recursively across multiple directories? ![]() Example 1: Grep for “test” string under any symlinks and file under /tmp/dir.Grep recursively for files with symbolic links Example 2: Grep for multiple strings in single file.Example 1: Grep multiple patterns inside directories and sub-directories.Grep for multiple patterns with recursive search Method 4: using find with xargs (prune).Method 3: using find with xargs (NOT operator).Method 1: using find with exec (NOT operator).Grep for string by excluding pre-defined files Example 1: Grep for exact match recursively.Grep exact match in a file recursively inside all sub-directories Example 1: Search for string “test” inside /tmp/dir recursively.Grep for string in a file recursively inside all sub-directories \(expr \) : True if ‘expr’ is true used for grouping criteria combined with OR or AND. ![]()
