sed with literal string ( sed: no input files )-CodePudding

This should be easy: I want to run sed against a literal string, not an input file. If you wonder why, it is to, for example edit values stored in variables, not necessarily text data.

When I do:

cat getGCC_MSISDN.tsk | sed -i 's/TEMP_MSISDN/'$1'/g' | java_gcc_soap_any.ksh

What should be the correct command? I want it to take my MSIDN from the file.

CodePudding user response：

Use printf to print the literal string.

printf '%s\n' 'some_literal_string' | sed -i 's/TEMP_MSISDN/'$1'/g' | java_gcc_soap_any.ksh

CodePudding user response：

You can try things like:

printf '%s' "$s" | sed "s/TEMP_MSISDN/$1/g" | java_gcc_soap_any.ksh

but that is very fragile. If $1 contains /, for instance, this will fail. You can try to fix that with things like:

printf '%s' "$s" | sed "s@TEMP_MSISDN@$1@g" | java_gcc_soap_any.ksh

but you're just trading one bad symbol for another and not really making the solution robust. If you are using bash, you can also try things like:

printf '%s' "${s/TEMP_MSISDN/$1}" | java_gcc_soap_any.ksh
