I'm trying to do script to change all occurrences of xpto
to abcd
in all .java
files in windows 10 system. The script is like above and run in git bash:
$find -path './*/*.java' | xargs -i sed -i 's/xpto/abcd/g' {}
But when I got to check the output files, all of them including the files without xpto
have changed endlines to LF
. I thought I'd run another script to change the endlines to CRLF
but in the folder have files with CRLF
and LF
and they need to keep the original endline.
EDIT 1
For reproduce the problem follow the steps above:
$printf '%s\r\n' 'first xpto' 'second xpto' > crlf.java
$printf '%s\n' 'first xpto' 'second xpto' > lf.java
$find -path './*.java' | xargs -i sed -i 's/xpto/abcd/g' {}
crlf.java
and lf.java
files will be with lf
endlines
CodePudding user response:
This isn't a generic sed
problem, but rather specifically an issue with with the msys-based version of sed included with the Git for Windows.
One can work around it with some extra logic:
find . -name '*.java' -print0 | while IFS= read -r -d '' file; do
IFS= read -r first_line <"$file"
if [[ $first_line = *$'\r' ]]; then
is_dos=1
else
is_dos=
fi
sed -i -e 's/xpto/abcd/g' -- "$file"
(( is_dos )) && unix2dos "$file"
done
