How to remove all of the diacritics from a file?
bash, replace, sed
Solution
If you check the man page of the tool `iconv`:
//TRANSLIT When the string "//TRANSLIT" is appended to --to-code, transliteration is activated. This means that when a character cannot be represented in the target character set, it can be approximated through one or several similarly looking characters.
so we could do :
kent$ cat test1
Replace ā, á, ǎ, and à with a.
Replace ē, é, ě, and è with e.
Replace ī, í, ǐ, and ì with i.
Replace ō, ó, ǒ, and ò with o.
Replace ū, ú, ǔ, and ù with u.
Replace ǖ, ǘ, ǚ, and ǜ with ü.
Replace Ā, Á, Ǎ, and À with A.
Replace Ē, É, Ě, and È with E.
Replace Ī, Í, Ǐ, and Ì with I.
Replace Ō, Ó, Ǒ, and Ò with O.
Replace Ū, Ú, Ǔ, and Ù with U.
Replace Ǖ, Ǘ, Ǚ, and Ǜ with U.
kent$ iconv -f utf8 -t ascii//TRANSLIT test1
Replace a, a, a, and a with a.
Replace e, e, e, and e with e.
Replace i, i, i, and i with i.
Replace o, o, o, and o with o.
Replace u, u, u, and u with u.
Replace u, u, u, and u with u.
Replace A, A, A, and A with A.
Replace E, E, E, and E with E.
Replace I, I, I, and I with I.
Replace O, O, O, and O with O.
Replace U, U, U, and U with U.
Replace U, U, U, and U with U.
Problem
I have a file containing many vowels with diacritics. I need to make these replacements: - Replace ā, á, ǎ, and à with a. - Replace ē, é, ě, and è with e. - Replace ī, í, ǐ, and ì with i. - Replace ō, ó, ǒ, and ò with o. - Replace ū, ú, ǔ, and ù with u. - Replace ǖ, ǘ, ǚ, and ǜ with ü. - Replace Ā, Á, Ǎ, and À with A. - Replace Ē, É, Ě, and È with E. - Replace Ī, Í, Ǐ, and Ì with I. - Replace Ō, Ó, Ǒ, and Ò with O. - Replace Ū, Ú, Ǔ, and Ù with U. - Replace Ǖ, Ǘ, Ǚ, and Ǜ with Ü. I know I can replace them one at a time with this: ``` sed -i 's/ā/a/g' ./file.txt ``` Is there a more efficient way to replace all of these?
