[英]comma separated values to single inverted quote and comma separated values
I have data as 我有数据
abc,defg,hijklm,op,qrs,tuv
I want this data to be converted to 我希望将这些数据转换为

I want to do in linux. 我想在linux中做。 I used "sed".
我用“ sed”。 I have been looking all over internet,but didnot come across a solution.
我一直在寻找整个Internet,但是没有找到解决方案。 Please help me.
请帮我。
Add a single quote at start ( ^
) & end ( $
), and replace comma by quote-comma-quote (like you did) using sed with 3 expressions (using -e
option to specify them): 在开始(
^
)和结束( $
)处添加一个单引号,并使用sed和3个表达式(使用-e
选项指定它们),用quote-comma-quote替换逗号(就像您所做的那样):
echo abc,defg,hijklm,op,qrs,tuv | sed -e "s/^/'/" -e "s/\$/'/" -e "s/,/',\'/g"
(also: protect single quotes with double quotes) (另:用双引号保护单引号)
results in: 结果是:
'abc','defg','hijklm','op','qrs','tuv'
in awk
(maybe a little clumsy), generally better since field parsing is handled natively by awk
: 在
awk
(可能有点笨拙),通常更好,因为字段解析是由awk
本机处理的:
echo abc,defg,hijklm,op,qrs,tuv | awk -F, "{for (i=1;i<=NF-1;i++) printf(\"'%s',\",\$i); printf(\"'%s'\",\$i);}"
(print all fields plus comma except for the last one) (打印除最后一个字段外的所有字段加逗号)
Using awk
gsub
function. 使用
awk
gsub
函数。 Here all the " ,
" are replaced by ','
and start and the end of the line is replaced by " '
". 这里所有的“ ”被取代
,
','
并开始和该行的端改为“ '
”。
echo $x |awk -v q="'" '{gsub(/,/, q "&" q);gsub(/^|$/,q)}1'
'abc','defg','hijklm','op','qrs','tuv'
awk '{gsub(/,/,"\47,\47");print "\47"$0"\47"}' file
'abc','defg','hijklm','op','qrs','tuv'
另一个awk
$ awk -F, -v OFS="','" -v q="'" '{$1=q $1; print $0 q}' file
