Answers: Ubuntu Linux: find files between specific times?

digitaltoast

I found an SO called using Find/Grep to search files between specific time of day

Based on that and a Unix SE called Grep command to find files containing text string and move them I ended up with:

find . -type f -mtime -20 | grep -v -e " \(0[012345]\|18\|19\|2[0123]\)" | xargs mv -t daytime/

But it's moving ALL the files. Does it make a difference that I'm using Ubuntu?

All I want to do is move all files between 6am and 6pm to another directory. Any suggestions would be appreciated.

Actually, find already has this functionality:

find . -newermt "2013-01-01 00:00:00" ! -newermt "2013-01-02 00:00:00"

From the manpage:

-newerXY reference
       Compares  the timestamp of the current file with reference.  The
       reference argument is normally the name of a file  (and  one  of
       its  timestamps is used for the comparison) but it may also be a
       string describing an absolute time.  X and  Y  are  placeholders
       for other letters, and these letters select which time belonging
       to how reference is used for the comparison.

       a   The access time of the file reference
       B   The birth time of the file reference
       c   The inode status change time of reference
       m   The modification time of the file reference
       t   reference is interpreted directly as a time

       Some combinations are invalid; for example, it is invalid for  X
       to  be t.  Some combinations are not implemented on all systems;
       for example B is not supported on all systems.  If an invalid or
       unsupported  combination  of  XY  is  specified,  a  fatal error
       results.  Time specifications are interpreted as for  the  argu‐
       ment  to the -d option of GNU date.  If you try to use the birth
       time of a reference file, and the birth time  cannot  be  deter‐
       mined,  a  fatal  error  message results.  If you specify a test
       which refers to the birth time of  files  being  examined,  this
       test will fail for any files where the birth time is unknown.

linux - Find words in many files

linux command-line find grep

ant2009

I am looking for this struct messages_sdd_t and I need to search through a lot of *.c files to find it. However, I can't seen to find a match as I want to exclude all the words 'struct' and 'messages_sdd_t'. As I want to search on this only 'struct messages_sdd_t' The reason for this is, as struct is used many times and I keep getting pages or search results.

I have been doing this without success:

find . -type f -name '*.c' | xargs grep 'struct messages_sdd_t'

and this

find . -type f -name '*.c' | xargs egrep -w 'struct|messages_sdd_t'

Many thanks for any suggestions,

Use ack:

ack "struct messages_sdd_t" *.c

It is recoursive by default and it is a lot faster than grep (according to my observation) when searching trough a directory containing tons of source code.

If you don't want to use ack, grep should be fine too:

grep -r "struct messages_sdd_t" *.c

Ignacio Vazquez-Abrams

find . -type f -name '*.c' -exec grep 'struct\s\+messages_sdd_t' {} \;

Or if you only care about the filename:

find . -type f -name '*.c' -exec grep -q 'struct\s\+messages_sdd_t' {} \; -print

Daniel Andersson

grep -R --include='*.c' 'struct messages_sdd_t' .

This will search recursively and use grep itself to pick only .c files.

Consider adding -H to always write the file name with the line match.
