[SOLVED] Replacing \ with "" gives ^ unterminated string

threezerous · 09-17-2014, 01:07 AM

I am trying to run my custom script on a set of grep results using the command

Code:

<custom script> | grep ^search_query: | awk '{print $NF}'

This return a result like
xyz:test\[Soluta incorrupte id\]

I need to get rid of \ character before I run my script (I am guessing they were added as escape characters)

So I modified my call as

Code:

<custom_script> | grep ^search_query: | awk 'gsub("\","");{print $NF}'

which gives me the error
awk: gsub("\","");{print $NF}
awk: ^ unterminated string

I tried a few other things using sed, but could not make it work.

Any suggestion? Thanks much to all

Perhaps?

Code:

<custom_script> | grep ^search_query: | tr -d '\\'

Use

Code:

awk '{gsub(/\\/,"")}1'

So your command should be

Code:

<custom_script> | grep ^search_query: | awk '{gsub(/\\/,"")}1'

It works for

Code:

echo "xyz:test\[Soluta incorrupte id\]" | awk '{gsub(/\\/,"")}1'

I do not like that grep|tr|awk -like chains, so:
<custom script> | awk '/^search_query:/ { gsub("\\\\",""); print $NF }'
