Bash 脚本 - 需要找到 output 文件路径的命令，用双引号括起来，不带换行符

Question

I have been using cscope/ctags database. However after sometime I noticed that some files in my cscope.files that stores the result of my find command, are broken into two or more lines. This causes them being ignored by cscope/ctags while indexing.

Currently I use it in an alias:

alias prp_indx='
    rm cscope.in.out cscope.out cscope.files tags
    find . -name '\''*.[chS]'\'' >> cscope.files
    find . -name '\''*.cpp'\'' >> cscope.files
    find . -name '\''*.hpp'\'' >> cscope.files
    find . -name '\''*.cxx'\'' >> cscope.files
    find . -name '\''*.hxx'\'' >> cscope.files
    cscope -b -q -k; ctags -R
'

Please help me with an appropriate command that I can use in my alias/function to achieve the file names with double quotes without paths broken in many lines.

Answer 1

There is no reason I can think of for find to split the file names in several lines, except if the names themselves have newline characters in them. If it is the case it is probably better to rename these files. Else there must be something else that tampers with your cscope.files file.

Prefer a function. Compared to functions aliases mainly have drawbacks. With a bash function:

prp_indx () {
  rm cscope.in.out cscope.out cscope.files tags
  find . -name '*.[chS]' -o -name '*.[ch]pp' -o -name '*.[ch]xx' > cscope.files
  cscope -b -q -k
  ctags -R "$@"
}
