Question

我尝试将文本文件的basename作为新行插入到整个文件目录的同一文件中（所有文件都有不同的basenames）。所以文件＆＃34; frog.txt ＆＃34;内容：

asdf
wef
sdf

...变为：

frog
asdf
wef
sdf

Answer 1

你可以试试这个bash one-liner：

for file in "sample1.txt" "sample2.txt"; do sed -i "1i${file%%.*}" "$file"; done

这将遍历每个文件名。 ${file%%.*}将从$file移除扩展程序。然后sed -i '1...'将插入文件名（不带扩展名）作为第一行。

Answer 2

在包含文件的目录中尝试：

for file in `ls`
do
# echo filename without extension to filename.tmp
# because you wrote .txt ${file:0:-4} removes 4 characters from the end
echo ${file:0:-4} >> $file".tmp"

# set IFS to split lines
IFS=$(echo -en "\n\b")

# echo line by line to filename.tmp
for line in `cat $file`
do
echo $line >> $file".tmp"
done 

# rename/move filenname.tmp to filename
mv $file".tmp" $file
done

# set IFS to normal
unset IFS

将基本名称添加到文本文件
