A search tool for logfiles that improves on findstr.
If you are looking for a search tool, you probably want ripgrep, which is much faster and more complete.
lgrep is not particularly fast, but its speed is comparable to the original findstr. Its redeeming features are
- one single source code file.
- compilable on any modern windows system without installing a huge tool chain.
- compatible command line switches to findstr.
- XML support.
First clone the repository, or copy the source file lgrep.cs.
git clone https://github.com/lroobrou/lgrep
Then, compile it:
C:\WINDOWS\microsoft.net\Framework64\v4.0.30319\csc.exe lgrep.cs /o
LGREP [/B] [/E] [/R] [/S] [/I] [/V] [/P] [/F:file]
strings [[drive:][path]filename[ ...]]
** Search switches **
/B Matches pattern if at the beginning of a line.
/E Matches pattern if at the end of a line.
/R Uses search strings as regular expressions.
/I Specifies that the search is not to be case-sensitive.
/V Prints only lines that do not contain a match.
/C:string Uses specified string as a literal search string.
/CS:string Uses specified string as a code to match a line.
** File Selection switches **
/S Searches for matching files in the current directory and all
subdirectories.
/P Skip files with non-printable characters.
/CW:file Use the treewalker coded in this file.
** Display switches **
/L Prints the line number before each line that matches.
/N Prints the number of matches.
/M Prints only the filename if a file contains a match.
/FN Don't print the filename if a file contains a match.
/PROGRESS Show a progress bar of the scan
** Context switches **
/CA:number Give n number of lines of context after any match
/CB:number Give n number of lines of context before any match
/CAS:string Give context after any match until the appearence of this string
/CBS:string Give context before any match as from the appearence of this string
The string matching context function can be used in conjunction with a number
in which case the minimum of both conditions will apply. Standard limit to
string matching context is 1000 lines.
** Data scan switches **
/SB:number Skip n bytes of each file before scanning for matches
/SP:number Skip n percent of each file before scanning for matches
/PL:number StoP after n lines in each file
** XML Mode **
/XP:string Don't scan lines, but scan the result of an XPath query
(see http://en.wikipedia.org/wiki/XPath)
/XPP Pretty Print XML Content
Some options don't apply in Xml mode
********************
strings Text to be searched for.
[drive:][path]filename
Specifies a file or files to search.
Use spaces to separate multiple search strings unless the argument is prefixed
with /C. For example, 'LGREP ""hello there"" x.y' searches for ""hello"" or
""there"" in file x.y. 'LGREP /C:""hello there"" x.y' searches for
""hello there"" in file x.y.
Regular expression quick reference:
. Wildcard: any character
* Repeat: zero or more occurrences of previous character or class
^ Line position: beginning of line
$ Line position: end of line
[class] Character class: any one character in set
[^class] Inverse class: any one character not in set
[x-y] Range: any characters within the specified range
\x Escape: literal use of metacharacter x
\<xyz Word position: beginning of word
xyz\> Word position: end of word
