Remember your pearls [was grep, maybe]
Not an answer to the OP, but a follow-on. So, you've worked out a magnificent one-liner solution to a interesting and recurring task. How do you 'remember' your solution? Do you create a file with scripts and comments? Do you post it in a wiki? A blog? An IDE with snippets? Do you remember it in your head? I used to store my good one-liners in Konsole as 'bookmarks' because you could put anything into a bookmark. Until KDE4. They "improved" the bookmark system which now only knows telnet:// and ssh:// "URLs". Konsole even re-writes your bookmarks as you save them by url-encoding them. The issue is apparently due to reliance on Kurl - a core class in KDE, and so "not a problem" with Konsole. http://bugs.kde.org/show_bug.cgi?id=185962 http://bugs.kde.org/show_bug.cgi?id=88867 Greg Rundlett nbpt 978-225-8302 m. 978-764-4424 -skype/aim/irc/twitter freephile http://profiles.aim.com/freephile ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Interesting point. Three replies: 1) If you're mv'ing onto the same filesystem, the inodes will never change, and it won't matter. 2) I imagine grep will only spit out a status (which is what the "&&" parses) after it's finished running, though I'd have to verify that empirically. 3) You can cheat, and do something like this: cat "$i/*" | grep -l moe && mv "$i" /destpath || echo "mv didn't work: $?" -Ken On Thu, October 29, 2009 4:41 pm, Ben Scott wrote: > On Thu, Oct 29, 2009 at 2:31 PM, Ken D'Ambrosio wrote: > >> find -type d | while read i do grep moe "$i/*" && mv "$i" >> /path/to/destination || echo "mv didn't work: $?" >> done > > Hmmm, does the "find" execute concurrently with the "grep"?

I didn't know about the "--target-directory" option to mv(1). That'll come in handy in the future. Thanks... Hmmm, file names with spaces are likely to foul things; xargs splits on any whitespace by default.

I'd probably go with something like:
grep --recursive --files-with-matches "$searchstring" "$topdir" \
| xargs --max-args=1 dirname \
| sort --unique \
| xargs mv --target-directory="$newloc"
The only thing that really sucks about that is that the involvement of
`sort' means that the mv needs to wait until *all* of the files have
been grep'd, instead of just moving the directory as soon as *any*
file in it is found to contain the search-term.
And, depending on whether your directories vary in the depth of their
nesting, and whether you prefer to move the more- or less-deep
directories first (or at all), you may need to add a "--reverse" to
the `sort' line or do more complicated filtering with an additional
grep (on the *paths*) or sed.

You'll have to come up with a way to create the value for "new location
here" that is unique so you don't overlay all the directories into the same
path and lose everything, so maybe test it with a copy first. You'll also
want to check /tmp/grep.errs for any error messages. I hope this helps.

Well, the following will search for any file containing "moe" (exactly), and list matching files: grep -l -r moe /path/to/top/level/directory If you want a case-insensitive search (match "moe", "Moe", "MoE", etc.): grep -i -l -r moe /path/to/top/level/directory If you want to search for multiple names, separate them by vertical bars (|). You will have to quote the search string to keep the bars from being interpreted by the shell: grep -i -l -r 'moe|larry|curly' /path/to/top/level/directory Moving just the files would be pretty easy. Moving the *directories* would be trickier. We can't move it when grep is still in the directory, so we'll have to save a list somewhere, then parse the list to find the directory names, then eliminate the duplicates, then move the directories. -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
Re: grep, maybe
grep -r greps all files recursively. grep -l outputs only the names of files which contain matching text. To move the folders, you would have to process that output to select the directory, then move the directory. Probably a perl or shell scripting task. AFAIK grep has nothing so specific as moving the folders the files are in, but it gets you 80% of the way there. --DTVZ On Thu, Oct 29, 2009 at 11:38 AM, Maurice wrote: > Looking for some guidance; > > I have several files within several folders (5 files per folder, and > thousands of folders) that I need to search a text file within each > folder for a word match (like three_little_pigs.txt, and I need to find > "moe", if he's listed) and then when a match is found I need to move > (not copy) that entire folder (and it's 3~5 files contained within) to > another location... > > I'm thinking grep, but don't know the correct syntax to make all this > happen. > I can easily find all the folders (1949 of them) and the word match 3923 > times within the text file(s)... > > > Any ideas??? > > > > -- > -Maurice Pelletier > Child Development Services - Cumberland County > 50 Depot Road > Falmouth, ME 04105 > 207-781-8881 (voice) > 207-781-8855 (fax) > > www.cds-cumberland.org > > > "Linux -- it's not just for breakfast anymore..." > -Moe > > > > ___ > gnhlug-discuss mailing list > gnhlug-discuss@mail.gnhlug.org > http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/ > ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
grep, maybe
Looking for some guidance; I have several files within several folders (5 files per folder, and thousands of folders) that I need to search a text file within each folder for a word match (like three_little_pigs.txt, and I need to find "moe", if he's listed) and then when a match is found I need to move (not copy) that entire folder (and it's 3~5 files contained within) to another location... I'm thinking grep, but don't know the correct syntax to make all this happen. I can easily find all the folders (1949 of them) and the word match 3923 times within the text file(s)...

landscape architecture software
I wanted to do some modelling of my home landscaping. Anyone know of an application that does this (Linux-compatible of course)? There are many software packages available for Windows, but I can't seem to find any that are linux compatible. I thought to try my hand at using Blender, but I'd really like to use something that is specifically pre-tooled to deal with landscaping. For example the commercial Windows packages have thousands of photorealistic plants and things that you can add to your models.
