遍历除某些文件以外的文件的脚本

Question

I'm trying to loop through all HTML files in a directory.

The following works just fine for that.

for f in *.html; do echo $f; done

But, how can I add an if condition so that the file name is only echoed if it is not equal to index.html ?

Answer 1

It should be simple like:

for f in *.html
do 
    if [ "$f" != "index.html" ]
    then
        echo $f
    fi
done

Answer 2

for f in *.html; do  [ "$f" != "index.html" ] && echo "$f"; done

Answer 3

It's also possible to exclude index.html from the list entirely with extended globbing :

shopt -s extglob nullglob
for f in !(index).html; do
    echo "$f"
done

• shopt -s extglob : enables extended globbing
• shopt -s nullglob : makes sure the loop is not executed should there be no matching files
• !(index).html : expands to all html files that are not index.html
