xargs: unmatched single quote
I was learning some shell commands in a little more detail when I came across this situation:
I made a file by the name of foo, by giving this command. (pwd is /home/akudewan/files/)
So, I did:
I made a subdirectory and did a "cd" to ~/files/temp/. Then I copied foo.txt here and also made another file "file.txt" I changed the command to:
My best guess is that the output of find contains a single quote.
One remedy for this could be:
$ find -type f | grep -ve "'" | xargs ...
perhaps you could post the output of these commands:
$ find --version
$ grep --version
$ xargs --version
PS. "pwd is /home/akudewan/files/" is _slightly_ incorret: pwd is an abbreviation for 'print [current] working directory', whereas cwd is 'current working directory' (or something to that effect). Thus, it would have been more correct to say "cwd is /home/akudewan/files". I hope you don't think of this as criticism, I'm just trying to enlighten you ;)
Thanks jonaskoelker. There was a file that had a single quote (bruce lee's jeet kune do.pdf) ;)
I renamed that file and the command worked perfectly. But how do I go about it if there is a quote?
fixing the quotes:
$ find -type f | sed -e "s/'/\\'/g" | xargs grep -e 'some regex...'
the sed call translates all "'" into "\'" (quote to backslash quote).
In case you have files containing other funny characters (# and " in particular), you may want to escape those as well.
have a look at either 'man sed' or 'info sed'.
Also, you might want to upgrade grep, find and xargs (I run 2.5.1 and 4.1.20 x 2, respectively).
hope this helps,
Thanks for all the help jonaskoelker. I'll look into this more on google and on the man pages. I've got the overall gist.
