Based on the information at https://tex.stackexchange.com/questions/48933/which-symbols-need-to-be-escaped-in-context, I want to prepare a file for use with ConTeXt. I need to make several replacements:
Replace # with \#.
Replace % with \percent.
Replace | with \textbar.
Replace $ with \textdollar.
Replace _ with \textunderscore.
Replace ~ with \textasciitilde.
Replace { with \textbraceleft.
Replace } with \textbraceright.
I have tried using the information from Replacing "#", "$", "%", "&", and "_" with "\#", "\$", "\%", "\&", and "\_" to do these replacements:
sed -i 's/\&/\\\&/g' ./File.csv
sed -i 's/\#/\\\#/g' ./File.csv
sed -i 's/\%/\\\percent/g' ./File.csv
sed -i 's/\|/\\\textbar/g' ./File.csv
sed -i 's/\$/\\\textdollar/g' ./File.csv
sed -i 's/\_/\\\textunderscore/g' ./File.csv
sed -i 's/\~/\\\textasciitilde/g' ./File.csv
sed -i 's/\{/\\\textbraceleft/g' ./File.csv
sed -i 's/\}/\\\textbraceright/g' ./File.csv
Unfortunately, when I run these scripts, the entire file is changed to a bunch of strange letters, numbers, and the words "extbar" everywhere.
How can I make these replacements?
Why is "extbar" appearing in my file after running these commands?
when you do
sed -i 's/|/\\\textbar/g' ./File.csv
sed reads it as s/|/\\\textbar/g \\ becomes \ and \t becomes tab character.
Try
sed -i "s/|/\\\textbar/g"
or
sed -i 's/|/\\textbar/g'
Use four backslashes instead of the to escape. They are evaluated twice. Following, you have the character \tas replacement, followed by the string 'extbar'(from \textbar)
This might work for you:
cat <<\! >Village.sed
s/&/\\&/g
s/#/\\#/g
s/%/\\percent/g
s/|/\\textbar/g
s/\$/\\textdollar/g
s/_/\\textunderscore/g
s/~/\\textasciitilde/g
s/{/\\textbraceleft/g
s/}/\\textbraceright/g
!
sed -f Village.sed ./File.csv
Not sure why "extbar" is appearing in your file probably to do with the line s/\|/\\\textbar/g where \| means alternation.
See here:
echo foo | sed 's/\|/\\bar/'
\barfoo
echo foo | sed 's/|/\\bar/'
foo

I have an text file, with line inside...
line: <version="AAA" email="...ANY..." file="BBB">
new desired line in text file to be: <version="AAA" email="NEW_TEXT" file="BBB">
I want to replace the ...ANY... expression with variable (replace entire line)
I have this script text-file script in #!/bin/bash, but I have problem when expanding double quotes in variables.
LINE_NUMBER="$(grep -nr 'email' *.txt | awk '{print $1}' | sed 's/[^0-9]*//g')"
VAR1="$(grep 'email' *.txt | cut -d '"' -f1-3)"
VAR2="$(grep 'email' *.txt | cut -d '"' -f5-)"
VAR3='NEW_TEXT'
NEW_LINE=$VAR1'"'$VAR3'"'$VAR2
new desired line in text file to be... <version="AAA" email="NEW_TEXT" file="BBB">
awk -i inplace 'NR=='"$LINE_NUMBER"'{sub(".*",'"'$NEW_LINE'"')},1' *.txt
but I get this new line:
<version="" email="NEW_TEXT" file="">
what do I do wrong?
How can I prevent expand duouble quotes inside variable?
please better write me an working example, I had tried other topics, forums, posts....but I have no luck.
You cas use sed :
VAR3='NEW_TEXT'
sed -i "s/email=\"[^\"]*\"/email=\"$VAR3\"/" myfile.xml
Suggesting:
var3="text space % special < chars"
Note var3 may not contain & which is special replacement meaning in sed
sed -E 's|email="[^"]*"|email="'"${var3}"'"|' input.1.txt
Explanation
[^"]* : Match longest string not having " till next ".
I'm trying to add a line in a file afile.xyz using my script. This is what I've done so far using sed:
n="$(grep ".method" "$m" | grep "onCreate(Landroid/os/Bundle;)V")"
sed -i '' -e '/$n/ a\
"test", /Users/username/Documents/afile.xyz
I'm getting the error:
"onCreate\(\Landroid\/ ...": bad flag in substitute command: 'g'
How do I solve this? Please do help. Thanks.
Edit: Content of n
method protected onCreate(Landroid/os/Bundle;)V
2 problems:
because the sed body is in single quotes, the variable $n will not be expanded,
the regular expression in $n contains the / dilimiters.
Try this:
n=$(...)
nn=${n//\//\\/} # escape all slashes
sed -i '' '/'"${nn}"'/ a ...
The single-quoted sed body is interrupted to append the double quoted shell variable.
You can also use a different delimiter for the RE:
sed -i '' -e "\#$n# a\\
\"test\"" /Users/username/Documents/afile.xyz
I have a folder with the name Translated_cds.
in this folder, there are 52 text files. these are FASTA files that have information about proteins.

the line starting with > (called the header)is present in all the files. I want to replace the gap ' ' in the headers with _.
till now i have tried this
sed -i 's/ /_/g' Translated_cds*
We can lead with /^>/ to gate the substitution so that it isolates to the pattern we are interested in:
sed -i -e '/^>/ s/ /_/g' Translated_cds*
My test:
echo '>lcl|NZ_JPMI01000003.1_prot_WP_043388330.1_1 [locus_tag=Q664_RS00010] [protein=HAMP domain-containing protein] [protein_id=WP_043388330.1] [location=complement(30..1904)] [gbkey=CDS]

If we want only the spaces within the keyword/value tags of the header replaced, then:
sed -i -e '/^>/ s/\([A-Za-z0-9]\) \([[A-Za-z0-9]\)/\1_\2/g' Translated_cds*
Or.... We can clarify a bit with more modern regex:
sed -i -E '/^>/ s/([[:alnum:]]) ([[:alnum:]])/\1_\2/g' Translated_cds*
The result will change only inside the header's keyword/value tags:
>lcl|NZ_JPMI01000003.1_prot_WP_043388330.1_1 [locus_tag=Q664_RS00010] [protein=HAMP_domain-containing_protein] [protein_id=WP_043388330.1] [location=complement(30..1904)] [gbkey=CDS]

Hello I'm sort of new to scripting and have the following problem
I need to replace 20069.1216.0
HintPath..\packages\String.20069.1216.0\lib\net\Thoo.Tkc.dll/HintPath
This works fine at replacing 20069.1216.0 with whatever is provided in $2
`xargs sed -i 's/String.20.........0/String.'"${2}"'/g'`
I need a way for sed to search for **"String.*\lib\net\"**where anything in between **String.** and **\lib...** is wildcard
This what i have tried
sed -i 's/String.*\/String.'"${2}"'/g'
sed -i 's/String.*\\/String.'"${2}"'/g'
sed -i 's/String.\(.*\)\\/String.'"${2}"'/g'
I'll assume that you call sed inside a function.
So try this code:
#!/bin/bash
replace() {
echo 'HintPath..\packages\String.20069.1216.0\lib\net\Thoo.Tkc.dll/HintPath' |\
sed "s/String\.[0-9.]*/String\.${2}/"
}
replace dont_care filename
If your path may contain --SNAPSHOT this solution should work for you:
#!/bin/bash
replace() {
echo 'HintPath..\packages\String.20069.1216.0--SNAPSHOT\lib\net\Thoo.Tkc.dll/HintPath' |\
sed "s/String[0-9.]*\(--SNAPSHOT\)\{0,1\}/String\.${2}/"
}
replace dont_care filename
My text file contains:
/**
*
**/
I want to replace the second line with text.txt so that it looks something like:
/**
* text.txt
**/
I tried the following sed command but it rendered the text file empty.
sed -n 2p -i -e "/^ \*/ s/ \*/ \* text.txt/" example.txt
Please let me know what I need to do to get the desired result.
sed -i -e "2s/$/ test.txt/" example.txt
if you want to do the replacement in line 2, specifically.
To add that to the line after /**
sed '/^\/\*\*/ {n; s/$/ text.txt/;}' example.txt
To replace the second line (independently on its content), use
sed -i -e '2c\ * test.txt' example.txt
2 addresses the second line, c\ replaces it with the rest of the argument
(\ is needed otherwise the space is omitted).
