Viewed k times. I want to do a: grep -lir "the string I am looking for" and get a list of all binaries inside a particular directory that contain that string but grep -lir is apparently not working with these files.
Is there a command that can do this kind of search from terminal? Improve this question. edited Jul 24, at cuonglm k 38 38 gold badges silver badges bronze badges. asked Jul 23, at Duck Duck 4, 17 17 gold badges 48 48 silver badges 63 63 bronze badges.

This binary is good fit for this task. xeon: It's not always good to use strings , read here for more details. Since the goal is to determine which binaries contain the string, strings -f would be more appropriate. This is a better answer. the best answer. thanks a lot — acgbox. With GNU grep , you can use -a option to make it treats binary files as text files: grep -ali -- string file If your grep version does not support -a , you can use ack instead. edited Nov 10, at cuonglm cuonglm k 38 38 gold badges silver badges bronze badges.
Am I misreading ack 's self-description? in the manual "ack 2. x will search through every regular, non-binary file that is not explicitly ignored [by blah blah]" So it sounds like ack 2. x should still stop reading a file early if the contents look binary.
PeterCordes: That's occured when no files were selected. I updated my answer to prevent confusing. Try using the strings command to get the strings from your binary. I often use grep -aPo '.

If the first few bytes of a file indicate that the file contains binary data, assume that the file is of type TYPE.
By default, TYPE is binary , and grep normally outputs either a one-line message saying that a binary file matches, or no message if there is no match.
If TYPE is without-match , grep assumes that a binary file does not match; this is equivalent to the -I option. If TYPE is text , grep processes a binary file as if it were text; this is equivalent to the -a option.
Suppress normal output; instead print a count of matching lines for each input file. With the -v , --invert-match option see below , count non-matching lines. If an input file is a device, FIFO or socket, use ACTION to process it. By default, ACTION is read , which means that devices are read just as if they were ordinary files. If ACTION is skip , devices are silently skipped. If an input file is a directory, use ACTION to process it. By default, ACTION is read , which means that directories are read just as if they were ordinary files.
If ACTION is skip , directories are silently skipped. If ACTION is recurse , grep reads all files under each directory, recursively; this is equivalent to the -r option. Interpret PATTERN as an extended regular expression see below. Use PATTERN as the pattern; useful to protect patterns beginning with -. Interpret PATTERN as a list of fixed strings, separated by newlines, any of which is to be matched.
Obtain patterns from FILE , one per line. The empty file contains zero patterns, and therefore matches nothing. Interpret PATTERN as a basic regular expression see below. This is the default. Suppress the prefixing of filenames on output when multiple files are searched. Ignore case distinctions in both the PATTERN and the input files. Suppress normal output; instead print the name of each input file from which no output would normally have been printed. The scanning will stop on the first match.
Suppress normal output; instead print the name of each input file from which output would normally have been printed. Stop reading a file after NUM matching lines.
If the input is standard input from a regular file, and NUM matching lines are output, grep ensures that the standard input is positioned to just after the last matching line before exiting, regardless of the presence of trailing context lines.
This enables a calling process to resume a search. When grep stops after NUM matching lines, it outputs any trailing context lines. When the -c or --count option is also used, grep does not output a count greater than NUM.
When the -v or --invert-match option is also used, grep stops after outputting NUM non-matching lines. If possible, use the mmap 2 system call to read input, instead of the default read 2 system call.
In some situations, --mmap yields better performance. Prefix each line of output with the line number within its input file. Show only the part of a matching line that matches PATTERN. Displays input actually coming from standard input as input coming from file LABEL.
This is especially useful for tools like zgrep, e. gzip -cd foo. Quiet; do not write anything to standard output. Exit immediately with zero status if any match is found, even if an error was detected. Also see the -s or --no-messages option. Read all files under each directory, recursively; this is equivalent to the -d recurse option. Recurse in directories only searching file matching PATTERN. Suppress error messages about nonexistent or unreadable files.
Portability note: unlike GNU grep , traditional grep did not conform to POSIX.

When type is binary, grep may treat non-text bytes as line terminators even without the -z option. This means choosing binary versus text can affect whether a pattern matches a file. 2/9/ · $ grep -a traceId ~/logs/blogger.com The -a option means on the man document for grep: a, --text Process a binary file as if it were text; this is equivalent to the --binary-files=text option This article demonstrates using the grep command along with its -a option to display the binary data on the shell.
