linux 下find 指令可以查詢指定路徑下的檔案或路徑
find . -type f | grep *** #-f 表示檔案 d 表示路徑 *** 表示檢索關鍵字
-h follow command line symlinks -l follow all symlinks
match filters:
-name pattern filename with wildcards (-iname case insensitive)
-path pattern path name with wildcards (-ipath case insensitive)
-user uname belongs to user uname -nouser user id not known
-group group belongs to group group -nogroup group id not known
-perm [-/]mode permissions (-=min /=any) -prune ignore dir contents
-size n[c] 512 byte blocks (c=bytes) -xdev only this filesystem
-links n hardlink count -atime n[u] accessed n units ago
-ctime n[u] created n units ago -mtime n[u] modified n units ago
-newer file newer mtime than file -mindepth n at least n dirs down
-depth ignore contents of dir -maxdepth n at most n dirs down
-inum n inode number n -empty empty files and dirs
-type [bcdflps] type is (block, char, dir, file, symlink, pipe, socket)
-true always true -false always false
-context pattern security context -executable access(x_ok) perm+acl
-newerxy file x=acm time > file's y=acm time (y=t: file is literal time)
numbers n may be prefixed by a - (less than) or + (greater than). units for
-xtime are d (days, default), h (hours), m (minutes), or s (seconds).
grep -nre "keyword" . #在當前目錄下的所有檔案中檢索關鍵字keyword
grep --help
-e regex to match. (may be repeated.)
-f file listing regular expressions to match.
file search:
-r recurse into subdirectories (defaults file to ".")
-r recurse into subdirectories and symlinks to directories
-m match filename pattern (--include)
-s skip filename pattern (--exclude)
--exclude-dir=pattern skip directory pattern
-i ignore binary files
match type:
-a show num lines after -b show num lines before match
-c num lines context (a+b) -e extended regex syntax
-f fixed (literal match) -a always text (not binary)
-i case insensitive -m match max many lines
-v invert match -w whole word (implies -e)
-x whole line -z input nul terminated
display modes: (default: matched line)
-c count of matching lines -l show only matching filenames
-o only matching part -q quiet (errors only)
-s silent (no error msg) -z output nul terminated
output prefix (default: filename if checking more than 1 file)
-h force filename -b byte offset of match
-h hide filename -n line number of match
