How do I pass xargs input one line at a time to subsequent command? For example I want to install rubygems by reading a text file as shown below, however the arguments are getting passed all at once to the 'gem install' command. I hace tried -L (max-lines) and -n (max args) options, but it didn't work. Wha...

...messages ID cut -b -14 file2 > file3 # prepend '*' to message IDs sed "s/^/\*/" file3 > file4 All of this works the way that I expect. What I now want to do is to mv all of the related files listed in file4 in the form "*messageid" to another directory. Using xargs I expected (naively) that the following construction would work: cat file4 | xargs mv /var/spool/mqueue/'{}' \ /var/spool/mqueue/offline (note that in the original this is all one line.) However, when I do this I get the error: mv: when moving multiple files, last argument must be...

...ot; - " in their filenames. I'm trying to adjust the permissions as well as user and group membership and i'd like the changes to be sticky. On the tld i've set permissions of 2755 and am trying to batch convert the files and subfolders in it. I've done this: find tld -type f |xargs chmod 644 {} \; find tld -type d |xargs chmod 755 {} \; Both of these are failing due to the spaces and dashes. I've tried enclosing those {} in quotes, no good. Has anyone done this with shell or perhaps perl? Thanks. Dave.

...those who've never used this option - for the GNU cp & mv type commands they have the --target-dir="dir" option. It lets you put the destination directory as the first argument to cp and mv instead of the last argument. They added the option to get cp & mv working well with xargs for stuff like this: find ./ -type file -mindepth 3 -print0 | xargs -r0 cp --target-dir=/home/sam/stuff/otherstuff/morestuff -- then xargs puts all of the files found by find after the -- Before I learned about this argument I used to do stuff like the "-i" and "-n" option...

Howdy, I am getting some errors with find and ls command - such that find is able to see a file whereas ls says the file doesn't exist. Initially I was trying find and ls together as: # find ./ -type f -mtime +15 | xargs ls Similar behavior is seen even when I execute both commands separately. Any thoughts on what might be wrong here? -- thanks, neubyr

Hi, I am trying to delete files that are more than 7 days old. When I run it interactively it works, no problem, but it does not run from a file stored in cron.daily. The rest of that daily file runs properly. [The execute bit is on].

...s best done at the time of the original file's creation. I am looking for a way to deal with multiple existing files in a batch fashion so that the reformatted file is written back out to the same file name oin the same location. I cannot seem to hit upon a way to get this to work using find, xargs and fmt (or fold). Nor can I seem to find an example of how this might be done using these utilities. What I would like to discover is the functional equivalent of this: find /path/to/archives/*.html -print | xargs -I {} fmt -s {} > {} This syntax does not work of course because the xargs fi...
