I want to remove a pattern \textcolor{red}{ and replace }} by } from list of specific lines using bash Let say i have a file

cat A.txt

 \ParallelLText{\jverse{5}\textcolor{red}{“Ahut isi inut chili kerik abang chili rik damlo. Alangli chili kerik ahut penang achili ke tovar akungsi klolo, lapen la aphan dongpon long-lo lapen nampi avo atum vangsi chongthok-et-lo.}}{\jverse{5}\textcolor{red}{“A sower went out to sow his seed; and as he sowed, some fell on the path and was trampled on, and the birds of the air ate it up.}}
 \ParallelLText{\jverse{6}\textcolor{red}{Lapen akaprek achili ke longpak athak klolo, lapen lake kechingjok pen mamat chekedulo, pima hadak longle kecham avedet-lo.}}{\jverse{6}\textcolor{red}{Some fell on the rock; and as it grew up, it withered for lack of moisture. }}
 \ParallelLText{\jverse{7}\textcolor{red}{Akaprek achili ke ingsu kethe arong ajosi klolo, lapen ingsu kethe arong la pen the rap-rapsi la aphan petthip-lo.}}{\jverse{7}\textcolor{red}{Some fell among thorns, and the thorns grew with it and choked it.}}
 \ParallelLText{\jverse{8}\textcolor{red}{Jisu halatum aphan thak-lo, “Arnam Arat akepatu alam kechiniji, lake nangtum aphan nangpitang-lo, bonta akaprek atum aphan ke lamlir pensi thanlo. Lasi latum thek longbom setta thek longledetji lapen arjubom setta chini nedetji.” }}{\jverse{8}\textcolor{red}{He said, “To you it has been given to know the secrets of the kingdom of God; but to others I speak in parables, so that‘looking they may not perceive, and listening they may not understand.’}}
 \ParallelLText{\jverse{9}\textcolor{red}{“Bonta Lamlir athe lahelo: Chili ke Arnam alamlo.}}{\jverse{9}\textcolor{red}{“Now the parable is this: The seed is the word of God.}}
 \ParallelLText{\jverse{10}\textcolor{red}{Tovar akung keklo achili ke karjulong atumlo; latum kroikredetsi kejok kelongledetji aphan Diabol vangsi halatum aning arlo pen alam pondet-lo.}}{\jverse{10}\textcolor{red}{The ones on the path are those who have heard; then the devil comes and takes away the word from their hearts, so that they may not believe and be saved.}}

Let say i have a list of lines to remove the pattern is line 1 and line 3 so my final output after removing and replacing the pattern will be

 \ParallelLText{\jverse{5}“Ahut isi inut chili kerik abang chili rik damlo. Alangli chili kerik ahut penang achili ke tovar akungsi klolo, lapen la aphan dongpon long-lo lapen nampi avo atum vangsi chongthok-et-lo.}{\jverse{5}“A sower went out to sow his seed; and as he sowed, some fell on the path and was trampled on, and the birds of the air ate it up.}

I tried with this command but it is not working

VAR=\\texcolor{red}{
sed -i "1s/$VAR//;3s/$VAR//" A.txt

I know how to delete a pattern from all the lines but i don't know for specific line.

    Did you actually test your regex on all the lines? \t is special in sed (representing a tab character) so needs to be escaped again i.e. VAR=\\\\textcolor{red}{ – steeldriver Jun 22 at 15:59

Like @steeldriver said, you need to use 4 back slashes, so they are escaped properly, like so: VAR="\\\\textcolor{red}{". Your sed command should work without any changes. Also, you misspelled 'textcolor'.

Tested with below awk command and it worked fine

awk 'NR==1||3{gsub(/\\textcolor{red}/,"",$0);print $0}' filename

output

\ParallelLText{\jverse{5}{“Ahut isi inut chili kerik abang chili rik damlo.

  • Final output is not correct @Praveen Kumar BS – Biki Teron Jun 22 at 19:13
  • NR==1||3 will always be true; you would need NR==1||NR==3 I think – steeldriver Jun 22 at 22:45
