Sometimes you need read a file into an array as one array element per line. print0 | while read -d $'' file do cp -v "$file" /tmp done Processing filenames using an array Try to copy files to /tmp with spaces in a filename using find command and shell pipes: find. To process the output of find with a command, try as follows: find. Also, if the find command matches no files, the command will be run with no parameters on many commands (like cat) this will cause the program to. potentially creating additional problems. ![]() While IFS=: read userName passWord userID groupID geCos homeDir userShellĭone < /etc/passwd Using old good find command to process file names If any pathname contains a space, newline, or tab, its name will be split (file a b will be incorrectly parsed as two files, a and b). In order to search for a file with spaces in the name you either have to enclose the argument in quotes or escape the spaces. For example, while loop can be used to get all fields from /etc/passwd file. Now you know that if the field delimiters are not whitespace, you can set IFS. IFS=$SAVEIFS More examples using $IFS and while loop There are multiple solutions to this problem. By default $IFS is set to the space character. for loop uses $IFS variable to determine what the field separators are. However, if you try to process a for loop on file name with spaces in them you are going to have some problem. Filenames and Pathnames in Shell: How to do it Correctly David A.

Beware that in this case the path itself shouldnt contain a string test. ![]() ![]() It finds the files in the current working directory recursively, echoes the original file name ( p) and then a modified name ( s/test/spec/) and feeds it all to mv in pairs ( xargs -n2 ).

Filed under: Linux, Mac, Shell | Tags: bash, Linux, loop, Mac, newline, Shell, spaces |īASH for loop works nicely under UNIX / Linux / Windows and OS X while working on set of files. Many programs fail to work properly on filenames that include spaces, begin with dash (-), include newlines, and so on, because developers don't know how to do it properly. name 'test.rb' sed -e 'p s/test/spec/' xargs -n2 mv. Unfortunately it does not rename files with spaces in the name. Adding - will avoid problems with filenames starting with dashes (they won’t be interpreted as arguments by rm ). This will delete any file whose name contains a space the space is escaped so the shell doesnt interpret it as a separator.
