Unexpected substitution for & with sed

& is a special character meaning "the whole matched string" in the s/// command. Use \&.

Use any character as a command delimiter, here is an example:

sed -Ei "s|$k|$j|g" filename.txt

shell csv utf-8 sed

In addition to the special characters you can also make the commands a bit safer and shorter:

The result:

#!/bin/bashwhile IFS="," read orig htmldo    for fl in *.php    do        sed -i 's/'$orig'/'${html//&/\\&}'/g' "$fl"    donedone < "htm.csv"

Please add an example if it doesn't work for you. There could be other special characters which would have to be escaped.
